This week, the downward trend of polyester filament has not stopped, continuing to drop by 50-100 yuan/ton compared to last week. When will such continuous decline come to an end?   The thunder is loud, but the rain is light in the reduced harvest. Recently, with the continuous decline in polyester prices, news of reduced production for polyester filament has been rampant. Reports indicate that two factories in Wuxi have shut down for maintenance, with one having a capacity of 240,000 tons and the other 400,000 tons. Two leading enterprises in Tongxiang have a combined maintenance of 1.645 million tons of capacity (1.495 million tons + 150,000 tons). A large factory in Xiaoshan has a 150,000-ton unit undergoing maintenance, while an 80,000-ton unit in a factory in Shaoxing has stopped production. The Ningbo region has seen particularly concentrated reductions, involving multiple companies, including a complete shutdown of a 250,000-ton unit, maintenance of 144,000 tons and 120,000 tons units, and a complete closure of another 120,000-ton capacity. The northern and Shandong regions have also been affected, with a factory in Liaoning having a 200,000-ton unit undergoing maintenance, and a small enterprise in Weifang, Shandong, halting a capacity of 35,000 tons. If we add up all these capacities, the total amount involved reaches as high as 3.384 million tons, which is quite substantial. According to data statistics from Longzhong Information, in the recent week, the production of polyester filament reached 759,200 tons, an increase of 9,600 tons compared to the previous week, with a growth rate of 1.28%. The capacity utilization rate was 92.94%, an increase of 1.17 percentage points from the previous week. The production of polyester filament not only did not decrease but instead increased. From the current situation, this round of production cuts indeed seems to be all noise and no substance, and it has largely contributed to the downward trend in polyester filament prices.   No promotions, no selling silk. Although the reduction in polyester filament production is insufficient and the output has increased instead of decreased, the final result is a continuous increase in inventory. With prices continuing to decline and a significant halt in production on the weaving side during the off-season, the downstream market is currently showing a clear wait-and-see attitude, with only essential purchases being made. Since late June, the production and sales of polyester filament have been mediocre. Last week, the weekly average production and sales rate of polyester filament was 37%. During the week, the overall production and sales rate of manufacturing enterprises was around 30-40%. Only on July 10 did the production and sales rate see a partial rebound, reaching around 200% on that day, with the average production and sales rate of sample enterprises exceeding 50%. This week, the weekly average production and sales of polyester filament has not shown significant improvement, remaining at only 38%, with production and sales under pressure. The inventory of manufacturing enterprises continues to grow. As of July 17, the inventory of polyester POY factories rose to 25.4 days, the inventory of polyester FDY factories increased to 25.6 days, and the inventory of polyester DTY rose to 30.7 days. Once the inventory comes under pressure, polyester factories begin to promote discounts, leading to a continuous decline in the price of polyester filament.   Polyester chips have started to reduce production. Although the reduction in polyester filament production is currently not as strong as expected, the reduction in another important area of polyester, polyester chips, is being carried out vigorously. On the evening of July 3, Wankai New Materials announced that, based on the overall industry situation and the company's production and operational needs, it plans to gradually adjust its PET production schedule starting from recent days, and will organize equipment maintenance during the reduction period. This production cut and maintenance will involve a PET capacity of 600,000 tons, accounting for 20% of the company's total capacity. According to statistics, between June and July, several leading companies have joined the production reduction campaign: China Resources Chemical has started to reduce production by 20% at its three factories since June 22, involving a capacity of 660,000 tons of polyester bottle flakes; Sanfangxiang has cumulatively stopped 1 million tons of capacity since the end of May, with no confirmed restart date; Yisheng plans to implement production cuts starting July 1, with a shutdown of 750,000 tons at its Hainan base and 350,000 tons at its Daqing base. This concentrated production reduction involves a total capacity of 3.36 million tons, accounting for 16.3% of domestic total capacity. As the plan progresses, the domestic polyester bottle flakes operating rate is expected to drop to around 75%. With the increased reduction in polyester chip production, the prices of polyester chips have begun to stabilize recently amid a decline in upstream raw materials, and profits have started to rebound. Perhaps it will be only when the major factories in the filament sector truly reach a consensus on production cuts, like in the slicing industry, that the price of polyester filament can return to stability.

Summary: On July 16, a summary of the prices and forecasts for general-purpose and engineering plastics in the market. Most general-purpose materials showed a downward trend, with PE market confidence lacking, falling by 15-29; PP lacked driving force, declining by 2-20; PVC inquiries were dull, dropping by 10-50; PS continued to decline, down by 10-50; ABS transactions were weak, decreasing by 30-60; EVA suppliers controlled the volume of shipments, with prices rising against the trend by 50-100. Engineering materials showed a steady downward trend, with PC weakly oscillating, up or down by 50-200; PBT and PA6 operated weakly, with some dropping by 100; PET, PMMA, POM, and PA66 remained stable.   General Material PE: Market confidence is insufficient, prices are declining. 1. Today's Summary 1. The U.S. sanctions plan against Russia will not be implemented in the short term, and coupled with OPEC+ continuing to increase production, international oil prices have fallen. NYMEX crude oil futures for the August contract are at $66.52, down $0.46 per barrel, a decrease of 0.69%; ICE Brent crude futures for the September contract are at $68.71, down $0.50 per barrel, a decrease of 0.72%. The price change range for the HDPE market is -24 to -15 yuan/ton, the LDPE market price is -29 yuan/ton, and the LLDPE market price is -15 yuan/ton. 2. Spot Overview The market's bearish atmosphere has not changed, and under the characteristics of off-season consumption, inventory pressure is increasing, while the market's price reduction and inventory reduction actions are suppressing the market. As prices continue to decline, transactions have slightly improved. The price change range for the HDPE market is -24 to -15 yuan/ton, the market price for LDPE is -29 yuan/ton, and the market price for LLDPE is -15 yuan/ton. 3. Price Prediction In the short term, regarding costs, there is an expectation for a decline in crude oil prices, which will weaken cost support; in the short term, the LDPE facility in Zhejiang Petrochemical and the LLDPE facility in Shanghai Secco will gradually resume operations, leading to a recovery in market supply. The demand in the agricultural film sector in North China is limited, and the overall supply-demand conflict remains unresolved, so polyethylene prices are still expected to operate weakly. Tomorrow The market price of polyethylene is mainly experiencing a slight decline.   PP: The market lacks obvious driving forces, and polypropylene prices fluctuate weakly. 1 Today's summary ①、 Sinopec Central China PP part adjustment: Sino-Korean low melt copolymer down 70 to 7130; high melt down 50 to 7350; Changling drawn wire and thin wall down 50, drawn wire 7000, thin wall 7300. ②、 Today, the domestic polypropylene shutdown rate remains unchanged from yesterday at 15.86%. The daily production share of yarn has increased by 0.10% from yesterday to 25.81%, while the daily production share of low melt copolymer has decreased by 1.42% from yesterday to 7.92%. ③、 (The supply and demand balance for this period from July 4 to July 10, 2025, remains in a situation where supply exceeds demand.) ， The supply-demand gap remains positive but has slightly decreased, which has somewhat alleviated the negative impact on market sentiment. In the next phase, the supply-demand balance is expected to expand its surplus, which is anticipated to intensify the negative impact on prices. 2 Spot Overview Table 1 Domestic Polypropylene Price Summary (Unit: Yuan/Ton) Market 7 15th of the month 7 16th of the month Change in value Price change percentage Nationwide 7120 7109 -11 -0.15% East China 7093 7091 -2 -0.03% North China 7089 7071 -18 -0.25% South China 7231 7221 -10 -0.14% Central China 7094 7074 -20 -0.28% Southwest 7120 7102 -18 -0.25% Northwest 7008 7008 0 0.00% Key downstream BOPP 8150 8150 0 0.00% Data source: Longzhong Information Based on the East China region, today's polypropylene filament is priced at 7091 yuan/ton, a decrease of 2 yuan/ton compared to yesterday. The national average price for filament is 7109 yuan/ton, down 11 yuan/ton from yesterday, which aligns with morning expectations. Today, the futures market is fluctuating at a low level, with some drops of 10-50 yuan/ton. The market sentiment remains bearish, and traders are offering discounts, leading to a downward shift in the spot prices. The low prices are stimulating buying interest from downstream, and the trading atmosphere in the market is still acceptable. As of noon, the mainstream price for wire rods in East China is between 7020-7160 yuan/ton. Figure 1 Domestic polypropylene price trend (unit: yuan/ton) Figure 2 Domestic Polypropylene Price Trend Chart by Region (Unit: Yuan/Ton) Data source: Longzhong Information Data source: Longzhong Information 3 Price prediction The production capacity of polypropylene continues to expand. Increasing supply pressure Market participants lack confidence in the future, and traders are primarily focused on reducing inventory by offering discounts for sales. The ongoing weakness in demand makes it difficult for the market to generate effective upward momentum, resulting in a lack of active market atmosphere. It is expected that the polypropylene market will continue to operate in a weak manner tomorrow, with mainstream prices for wire drawing in East China fluctuating around 7000-7150 yuan/ton, with a focus on changes in the cost and supply sides.   PVC: PVC inquiries are sluggish, and the price trend is weak. 1. Today's Summary The mainstream ex-factory price of domestic PVC production enterprises using the calcium carbide method has been adjusted down by 20-50 yuan/ton. The maintenance at the Fujian Wanhua plant has been gradually completed. New approach to urban work determined: demolition and reconstruction "makes way for" urban renewal. 2 Spot Overview Table 1 Summary of Domestic PVC Spot Prices (Yuan/Ton) Market Name 2025/07/16 Price change value Price Change Percentage PVC SG-5 4840 -10 -0.21% Yuan/ton   PVC SG-5 4880 -20 -0.41% Yuan/ton   PVC SG-5 4870 -20 -0.41% Yuan/ton   PVC SG-5 4700 -50 -1.05% Yuan/ton   PVC SG-5 4710 -10 -0.21% Yuan/ton   PVC SG-5 4670 0 0% Yuan/ton   Based on the Changzhou market in East China, today the cash price for calcium carbide method five in the East China region is 4840 yuan/ton, a decrease of 10 yuan/ton compared to the previous trading day. 。 The domestic PVC spot market remains subdued, with a clear contradiction between the expected increase in market supply and the lackluster terminal demand. The overall sentiment in the spot market is not optimistic, and the market is expected to maintain a weak state in the short term. In East China, the cash price for carbide-based PVC is between 4800-4920 yuan/ton, while for ethylene-based PVC it is between 4850-5100 yuan/ton. 3 、Price forecast During the week, maintenance schedules for PVC production enterprises have weakened, coupled with new production capacity starting trial runs, leading to a slight increase in market supply expectations. However, demand from downstream is affected by the off-season due to the heat and rainy season, resulting in a lack of orders and inquiries. Exports are also subdued as the market awaits next month's new pricing and developments regarding India's anti-dumping policies. Under the contradiction between supply and demand, market sentiment is weak, causing spot prices to fluctuate downward. In the short term, there are no policies or market expectation data to drive changes, with the anticipated cash price for calcium carbide method five-type in East China expected to be 4750-4850 yuan/ton.   PS: The market continues to decline, and trading is very sluggish. 1 Today's Summary Today, the price of East China GPPS dropped by 100, closing at 7850 yuan/ton. On Wednesday, styrene in the East China market rose by 5 to 7485 yuan/ton, while in South China it fell by 25 to 7565 yuan/ton, and in Shandong it dropped by 80 to 7560 yuan/ton. 2 Spot Overview Table 1 Domestic PS Price Summary (Unit: Yuan/Ton) Market Specifications Today's price Change in value Price fluctuation rate Ningbo East China GPPS - Green Anqing Peak 7850 0 -0.63% Yuyao East China HIPS - Saibolong 8800 -30 -0.56% Shantou South China GPPS - Renxin 7540 -10 0% Shantou South China HIPS - Xinghui 8470 -50 0% According to statistics from Longzhong Information, today the GPPS in East China is stable at 7,850 yuan/ton.The raw material styrene is weakly consolidated, with general cost support. The industry's capacity utilization rate is relatively low, but downstream demand is sluggish, resulting in a slow circulation of market supplies and poor transaction performance. 3 Price prediction Recently, the raw material styrene has fluctuated and declined, with weakened cost support. Industry supply is low, and downstream purchasing mainly remains on a just-in-need basis, leading to a weak price trend in the PS market in the short term. It is expected that the price of toluene in the East China market will be around 7800-8800 yuan/ton.   ABS: Demand off-season, today's market transactions are weak. 1 Today's summary: 1. Today, the prices in the East China market have slightly dropped; in the South China market, prices are declining, and market transactions are driven by just the basic need. In July, the monthly production of ABS is expected to increase compared to the previous month. 2 Spot Overview Table 1 Domestic ABS Price Summary (Unit: Yuan/Ton) Market Specifications 7 15th of the month 7 16th of the month Change value Price change rate Yuyao 15E1 10450 10450 0 0% 750A No price No price No price No price HI-121H 10150 10150 0 0% DG417 10000 10000 0 0% PA-757K 10550 10550 0 0% 0215A 10200 10200 0 0% Dongguan 15E1 9620 9620 0 0% 750A No price No price No price No price 121H 9250 9250 0 0% KF730 9580 9580 0 0% DG417 9430 9370 -60 -0.64% PA-757K No price No price No price No price 0215A 9300 9270 -30 -0.32% Data source: Longzhong Information Based on the regions of Yuyao and Dongguan, the market prices in East China are declining, and the market prices in South China are also declining. Today, the market transactions are very weak, with a sluggish demand season. Traders are offering discounts to sell their goods, and the market performance is lackluster. 3 Price Prediction: Based on the regions of Yuyao and Dongguan, the market prices in East China have slightly declined, and the market prices in South China have slightly declined. Today, the market transaction is weak, and prices are on the decline. With the demand in the off-season and raw material prices dropping, it is expected that ABS prices will continue to fall tomorrow.   EVA: Supplier controls quantity for shipment, market quotations push up prices. 1 Today’s summary This week, the EVA petrochemical ex-factory prices have been stable with a downward adjustment, and there are fewer auctioned goods available, with some soft material grades still experiencing tight spot supply. This week, the EVA petrochemical unit has been operating stably. 2.

Some grades of foamed soft materials are experiencing tight spot supply, with suppliers controlling the quantity of shipments. Additionally, delays in shipping in certain regions have contributed to the tight spot market. Holders are adjusting their prices upwards while maintaining stability, but downstream factories are resistant to high prices and transactions are still acceptable around lower price levels. Mainstream prices: soft materials reference 9,600-10,300 yuan/ton, hard materials reference 9,500-10,500 yuan/ton. 3 Price prediction In the short term, the supply side of the petrochemical spot supply is slightly tight for some foaming grades, while the photovoltaic inventory is mostly under no pressure. Suppliers are actively pushing prices up, and photovoltaic demand is progressing step by step. The foaming demand is in the off-season, and downstream factories are unlikely to have good order expectations. The supply and demand situation still remains in a tug-of-war. It is expected that the domestic EVA market will maintain a firm and stable trend in the near future. 。   Engineering materials PC: The market is weak and fluctuating. 1 Today's summary Tuesday International crude oil Downward ， ICE crude oil futures for the September contract are at $68.71, down $0.50 per barrel. ②、 Bisphenol A closing price in the East China market is 7875. Yuan/ton, remaining stable month-on-month. ③, Domestic PC factories have no latest factory price adjustment dynamics. 2 Spot Overview Today, the domestic PC market is operating in a narrow range at a low level. As of the afternoon close, the mainstream trading reference for low-end injection molding grade materials in East China is 10,350-13,900 yuan/ton, while mid-to-high-end materials are trading at 14,700-15,300 yuan/ton. Some mid-to-low-end material prices have decreased by 100-200 yuan/ton compared to yesterday. Domestic PC factories have no new factory price adjustment updates, and the online listed prices from Shandong PC factories remain stable compared to yesterday. In the spot market, both East China and South China are experiencing weak consolidation at low levels, with little fluctuation in the fundamentals. Overall bearish pressure remains, and market sentiment is cautious and difficult to uplift. Observing and following operations continue, with downstream purchasing on an as-needed basis being sparse, and the trading atmosphere remains quiet. 3 Price prediction Despite the fact that domestic PC prices are further approaching historical lows, the negative pressure on the industry has not diminished: the overall supply in the industry remains high, and affected by the traditional consumption off-season in July, downstream demand is generally weak, leading to an increasingly severe oversupply situation. Market trading conditions are difficult to improve, and the outlook remains cautious and bearish. It is expected that the domestic PC market will continue to fluctuate downward tomorrow.   PET: Polyester bottle chip market in a stalemate and consolidation 1 Today's Summary 1. Wankai lowered by 20, China Resources increased by 10, other factories remained stable. Unit: Yuan/Ton Today, the domestic polyester bottle chip capacity utilization rate is 71.19%. 2 Spot Overview Table 1 Domestic Polyester Bottle Chip Price Summary (Unit: Yuan/Ton) Market Specifications July 15th July 16 Change in value Price change percentage East China Aquarius Level 5925 5925 0 0% South China Aquarius Level 6000 6000 0 0% North China Aquarius 5930 5930 0 0% Based on the East China region, today's spot price for polyester bottle-grade chips is 5925, unchanged from the previous working day, basically in line with morning expectations. Crude oil continues to decline, raw material prices are fluctuating in a range, and most polyester bottle chip factories are holding their prices steady, with some adjusting by 10-20. The spot price for July cargo is 6010, and for August cargo, it is 5960-6000. The market is in a stalemate. It is heard that the transaction prices for July-August cargo are between 5850-5930, with downstream purchasing interest being weak and trading being light. Unit: Yuan/ton 3. Price Prediction Current market sentiment for goods is cautious and observing, with support from the raw material side continuously weakening. Although spot supply is ample, downstream purchasing willingness is low, resulting in light market trading. In the short term, the polyester bottle chip market is likely to maintain a weak and volatile trend, with the spot price expected to be 5850-5950 (unit: yuan/ton) in the East China market tomorrow.   POM: Market sales are slow, and trading activity is light. 1. Today's Summary The industry's shipments are under pressure. There are many low-priced market quotes. 2 Spot Overview Table 1 Domestic POM Price Summary (Unit: Yuan/Ton) Market Specifications July 15 July 16 Price change value Price change percentage Yuyao Yuntianhua M90 11300 11300 0 0.00% Dongguan Yuntianhua M90 10400 10400 0 0.00% North China Yuntianhua M90 11400 11400 0 0.00% Data source: Longzhong Information Based on the Yuyao region, today YunTianHua M90 is priced at 11,300 yuan/ton, stable compared to the previous period.Today, the POM market is generally stable with slight declines. There is no support from the fundamentals, and some factory prices are at low levels, putting significant pressure on operators. The market's sales situation continues to be weak, and there is little change in transaction activity. 3. Price Prediction Affected by the traditional demand off-season market, the transaction situation in various regions is unlikely to change significantly. Given that the petrochemical plant prices are at a low level, the downward space in the later market is limited. However, there are still some short-selling behaviors in the market, and the trading merchants' quotation focus will continue to decline. The pace of end-user orders is slow, and users' mentality towards taking over is relatively cautious, resulting in overall poor transactions. Longzhong expects that the domestic POM market will operate weakly in the short term.   PMMA: The PMMA market operates steadily with low demand. 1 Today's Summary Today, the factory's quotes are stable. The utilization rate of domestic PMMA particles today is maintained at 64%. 2 Spot Overview Based on the East China region, today's PM MA particles closed at 13,200 yuan/ton, unchanged from the previous working day, in line with morning expectations.Today, the domestic PMMA market is stable with slight fluctuations. The cost of MMA is weakly declining, providing limited support to the PMMA market. A small number of downstream companies are making inquiries based on demand, but actual transactions remain sluggish. There is pressure on suppliers to sell their inventory, and low-priced sources are occasionally reported in the market. The focus of actual trading is on a weak and fluctuating trend. 3 Price prediction The intraday cost side is fluctuating downward, coupled with persistently weak demand, making it difficult for the terminal to see significant improvement. PMMA manufacturers still have intentions to lower prices in the future, and traders are mostly observing, with low willingness to hold positions.   PBT: There is a limited supply of high-priced materials, and the PBT market is operating weakly. 1 Today's summary PBT manufacturers' quotes remain stable. This week, there are more repairs and load reduction operations for the PBT equipment. The PBT production for this period is 21,900 tons, remaining stable compared to the previous period, with a capacity utilization rate of 51.49%, also remaining stable compared to the previous period.This week, the average PBT gross profit in the domestic market is -322 yuan/ton, an increase of 42 yuan/ton compared to the previous week. 。 2 Spot Overview Table 1 Domestic PBT Price Summary (Unit: Yuan/Ton) Market Specification 2025/07/15 2025/07/16 Change value Price change percentage East China Low to medium viscosity pure resin 8100-8500 8100-8400 0/ -100 0%/ -1.18% Key upstream East China PTA 4712 4718 6 0.13% East China BDO (Sprinkling) 8550-8650 8550-8650 0/ 0 0%/ 0% Data source: Longzhong Information Based on the East China region, the mainstream price of medium and low viscosity PBT resin today is 8100-8400 yuan/ton, a decrease of 100 yuan/ton compared to yesterday's price. Today, the PBT market is running weak, the PTA market is adjusting prices, and the BDO market is operating steadily. The trend of raw materials is weak, and there is a strong bearish sentiment in the PBT market, with fewer high-priced sources available in the market. ， According to statistics from Longzhong Information, the price of low to medium viscosity PBT pure resin in the East China market is between 8100 and 8400 yuan per ton. 3 Price prediction The PBT market is expected to remain weak and cautious. On the raw material side, the PTA cost is showing a benign situation, but both supply and demand are weak, leading to a continued stalemate in the short-term PTA futures and spot markets. As the BDO settlement period approaches, market participants are paying more attention to the new policy cycle. With increasing supply and demand pressures, some holders are shifting to a bearish mindset and adopting a narrow profit margin strategy for sales, which may drag down the market’s focus and cause fluctuations. There are expectations of weakening raw materials, and PBT producers generally hold a pessimistic outlook for the future market. The mentality of buying on the rise and not on the fall has led to limited trading volume, with a potential for further weakening in market focus. Therefore, Longzhong expects that tomorrow, the mid-to-low viscosity PBT resin in the East China market will be priced between 8100-8400 yuan/ton.   PA6: Downstream sentiment is cautious with limited demand, and the PA6 market is operating in an adjustment phase. 1 Today's Summary The weekly settlement price for Sinopec caprolactam is 9,095 yuan/ton (six months acceptance interest-free), down 65 yuan/ton from last week. Sinopec's pure benzene prices at refineries in East China and South China have increased by 100 yuan/ton, now set at 5950 yuan/ton, effective from July 11. 2 Spot Overview Table 1 Summary of Domestic Nylon 6 Prices (Unit: Yuan/Ton) Market Specifications 7 15th of the month 7 16th of the month Change in value Payment terms Conventional spun slices of polyamide 6 Factory price (ordinary) 8950-9300 8950-9300 0/0 Cash factory Factory price (high-end) 9400-9800 9400-9700 0/-100 Cash out of factory East China Market (Ordinary) 9150-9500 9150-9500 0/0 Deliver to East China East China Market (High-end) 9400-9800 9400-9700 0/-100 East China self-pickup Nylon 6 high-speed spinning chips East China Spot (Ordinary) 9050-9400 9050-9400 0/0 Spot exchange factory East China Spot (Grade A) 9800-10000 9800-10000 0/0 Acceptance delivery Key upstream Caprolactam East China 8575 8600 +25 Acceptance delivery Data source: Longzhong Information Today, the nylon 6 market is operating with adjustments. The raw material market has seen a slight increase, putting pressure on chip costs. However, downstream enterprises are cautious, and demand is generally moderate, with purchasing mainly focused on just-in-time replenishment. Overall market transactions are average. In East China, the price for conventional nylon 6 is 9,150-9,500 yuan/ton cash on delivery, while the spot price for high-speed spinning is 9,800-10,000 yuan/ton on acceptance for delivery. The price in Chao Lake is 8,500-8,600 yuan/ton for cash and self-pickup. 3 Price prediction From the cost perspective, the caprolactam market may continue to operate in a range, as the cost pressure from chips remains. On the supply and demand side, the operating rate of domestic polymerization enterprises is temporarily stable, and supply is stable. However, the cautious sentiment from downstream leads to generally weak demand. It is expected that the PA6 market will operate in a range in the near term.   PA66: Downstream procurement based on demand, market operating in an orderly manner. 1 Today's summary 1. Longzhong 7/15: The U.S. sanctions plan against Russia will not materialize in the short term, coupled with the ongoing increase in OPEC+ production, leading to a decline in international oil prices. NYMEX crude oil futures for August contract are at $66.52, down $0.46 per barrel, a decrease of 0.69%; ICE Brent oil futures for September contract are at $68.71, down $0.50 per barrel, a decrease of 0.72%. China's INE crude oil futures main contract 2509 dropped by 2.6 to 509.3 yuan per barrel, and in the night session, it fell by 3.7 to 505.6 yuan per barrel. Today, the domestic PA66 capacity utilization rate is 57%, with a daily output of approximately 2,188 tons. Under the pressure of costs and demand, domestic PA66 enterprises have low capacity utilization rates, and the downstream demand is average, leading to a sufficient supply of goods in the domestic PA66 industry. 2 Spot Overview Table 1 Domestic PA66 Price Summary (Unit: Yuan/Ton) Market Specifications 7 15th of the month July 16 Change value Price change percentage East China EPR27 15750 15750 0 0% Key upstream East China Adipic acid 6950 6950 0 0% Data source: Longzhong Information Based on the Yuyao market in East China, today's market price for EPR27 is referenced at 15,700-15,800 yuan/ton, stable compared to yesterday's price. 。 Raw material prices are fluctuating within a narrow range, with stable support from costs. Downstream purchases are made based on demand, and the market supply of goods is sufficient, leading to a steady market operation. 3 Price prediction The terminal market demand is generally low, with downstream procurement based on demand. The supply of goods in the market is sufficient, and the fundamentals are relatively stable. It is expected that the domestic PA66 market will remain stagnant and consolidated in the short term.

Summary: Summary of April 2 plastic market general materials and engineering materials prices and forecasts! General materials show mixed trends, with limited improvement in supply and demand; polyethylene prices fluctuate slightly; PP sees a minor increase; PVC market falls by 10-20; ABS market fluctuates with increases and decreases, with a maximum increase of 250; PS and EVA markets fluctuate weakly and steadily. Most engineering materials remain stable, with PC seeing individual increases of 25-50; polyester chip prices drop by 10-20; POM sees the highest decrease of 150; PBT market centers weaken with fluctuation, with individual decreases of 50; PA6 market price increases by 50-200; PA66 and PMMA operate in a stalemate. General MaterialsPE：Market demand is limited, and the price of polyethylene fluctuates.1 Today's SummaryOn April 1st, the market focus shifted from sanctions on oil-producing countries to the U.S. tariff hike policy, with concerns that the demand outlook would be dragged down, leading to a fall in international oil prices. The NYMEX crude oil futures contract for May fell by $0.28 per barrel to $71.20, a decrease of 0.39% from the previous day. The ICE Brent crude oil futures contract for June, after the rollover, fell by $0.28 per barrel to $74.49, a decrease of 0.37% from the previous day. China's INE crude oil futures main contract 2505 rose by 11.6 yuan to 549 yuan per barrel, and during the night session, it increased by 4.3 yuan to 553.3 yuan per barrel.Today, the HDPE market price has been adjusted by 2-6 yuan/ton; the LDPE market price has risen slightly by 2 yuan/ton; the LLDPE market price has decreased slightly by 7 yuan/ton.2 Spot OverviewTable 1 Summary of Domestic Polyethylene Closing Prices (Unit: Yuan/Ton)Today, the domestic polyethylene spot market prices showed mixed trends. HDPE spot market prices made slight adjustments of 2-6 yuan/ton. Some maintenance and production changes led to a slight tightening of supply, but overall market demand remains limited, with end users showing clear resistance to high-priced resources, resulting in mainly minor price fluctuations. LDPE spot market prices rose slightly by 2 yuan/ton, with relatively stable LDPE supply and some improvement in downstream demand, leading to a slight increase in market quotations. LLDPE spot market prices fell slightly by 7 yuan/ton, with overall supply pressure in the market being significant, and no apparent improvement in downstream demand. Market participants are lacking confidence and are mostly maintaining active sales, resulting in continuous slight price declines.3. Price PredictionWith the approach of the Qingming long weekend, merchants maintain an active attitude towards selling goods. Supply pressure remains, so the price levels for most grades are still low. In the short term, with expectations of increased production from new facilities such as Exxon and Inner Mongolia Baofeng, terminal inquiries may target even lower prices. As a result, traders might be forced to offer discounts; however, strong cost support will remain. After low-end transactions pick up, it will provide market confidence, leading prices to likely remain in a narrow range at a low level. PP： Macro利好支撑 Polypropylene prices rise slightly1 Today's Summary① Sinopec Central China PP part adjusted downward: Luoyang wire drawing 7300, M18 to 7300; Zhonghan 8009 to 7600; Zhongyuan MT35 to 8050, MT75N to 7550.② Today, the domestic polypropylene shutdown impact decreased by 1.64% to 17.08%. Details of today's domestic PP maintenance facility changes: Zhongjing Petrochemical Phase II Line 2 (600,000 tons/year) PP facility has restarted. The daily production ratio of injection molding dropped by 2.08% to 25.41%, mainly due to the second line of Sinochem Quanzhou being switched to produce other products.This week (March 21-27, 2025), the supply and demand gap has narrowed significantly to 35,100 tons, mainly due to an increase in plant maintenance leading to a notable decrease in supply, coupled with demand still slowly recovering, resulting in an improvement in the supply and demand gap.2 Spot OverviewTable 1: Domestic Polypropylene Price Summary (Unit: Yuan/Ton)Based on the East China region, today's polypropylene filament closed at 7369 yuan/ton, an increase of 8 yuan/ton from yesterday, in line with the morning's expectations.Futures fluctuated slightly upward, with polypropylene prices consolidating within a range today. The implementation of tariff policies boosted the market, and the red futures market supported spot offers. However, terminal demand was lackluster, leading to mixed spot price movements. Market participants mostly followed the market trend, with actual transactions negotiated. As of midday, the mainstream price for drawing in East China was between 7320-7450 yuan/ton.Price ForecastAffected by the U.S. tariff policy, international oil prices may be dragged down by demand prospects, and the cost side is expected to provide limited support for polypropylene (PP). On the demand side, downstream procurement remains based on just-in-time needs, and is mainly focused on buying at low prices, which does not provide much boost to the market. On the supply side, there are currently no new capacity expansions, and in addition, short-term maintenance of production facilities remains relatively concentrated, so the supply pressure is still manageable. It is expected that the polypropylene market may experience range-bound fluctuations tomorrow, with mainstream prices for wire drawing in East China at 7,300-7,450 yuan/ton. PVC：Weak supply and demand, PVC spot prices remain volatile.1. Today's Summary① The ex-factory prices of domestic PVC producers have decreased by 20 yuan per ton respectively.2. During the startup of Qinzhou Huayi, the startup time for Yanhai Magnesium Industry's ethylene process is to be determined.③ The adjustment details for oil prices are as follows: the retail price limits for gasoline and diesel in China will be increased by 230 yuan and 220 yuan per ton, respectively. The price of No. 95 gasoline will increase by 0.19 yuan per liter.2 Spot OverviewTable 1 Summary of Domestic PVC Spot Prices (RMB/ton)Based on the East China Changzhou market, the spot cash pickup price for type five PVC produced by the calcium carbide method in East China is 4900 yuan/ton today, remaining stable compared to the previous trading day.。The domestic PVC market remains weakly volatile, with pessimistic expectations for macro policies. The spot market is mostly stable, with prices on the futures market mainly looking for lower levels. Export quotations have slightly decreased due to weakening demand. In the East China region, the cash price for warehouse delivery of calcium carbide method No. 5 type is between 4870-5000 yuan/ton, while the ethylene method is between 5000-5200 yuan/ton.3.Price forecastMeasureThe domestic PVC market is experiencing fluctuations and a weakening trend, with concerns about the impact of increased tariffs on raw material and product exports. The supply expectations for spot fundamentals have weakened due to maintenance, and domestic demand remains sluggish, with foreign trade exports being the main focus. Both supply and demand are lacking, leading to a weak and fluctuating spot price trend. In the short term, cost support remains stable, and it is expected that the PVC market will maintain a small range of weak fluctuations. The cash price for electric calcium carbide method PVC in East China is expected to be in the range of 4800-5000 yuan/ton. PS： Styrene rebounds and then fluctuates, market prices stabilize.1 Today's summary Today, the East China GPPS market remained stable at 8,400 yuan/ton, in line with the morning forecast.② On Wednesday, the styrene market in East China fell by 65 to close at 8,050 yuan/ton, South China dropped by 50 to 8,150 yuan/ton, while Shandong rose by 15 to 8,015 yuan/ton.2 Spot OverviewTable 1 Domestic PS Price Summary (Unit: RMB/ton)According to statistics, today the East China GPPS is stable at 8400 yuan/ton.Upstream styrene showed a slight rebound followed by consolidation, with the market mainly holding firm on prices. However, supply remains high, and overall market inventory is ample. After recent restocking, buyers have adopted a wait-and-see approach, leading to weaker trading activity compared to the previous day.3. Price PredictionThe frequent fluctuations in raw styrene have created significant uncertainty regarding cost support. With supply remaining high and demand falling short of expectations, there has been some improvement in low-end sales, but prices struggle to rise. In the near term, the PS market may consolidate within a narrow range. It is anticipated that the华东market for modified styrene will likely trade between 8,400 to 9,800 yuan per ton. ABS：The market for filling gaps has ended, and today's trading has turned subdued.1 Today's Summary:① Prices in South China rose and fell; prices in East China rose and fell, but overall transactions were good. 2. The monthly ABS production in April is expected to slightly decrease from the previous month.2 Spot OverviewTable 1 Summary of Domestic ABS Prices (Unit: Yuan/Ton)Based on the benchmarks of Yuyao and Dongguan regions, market prices have experienced both increases and decreases.Today's market trading has turned quiet, the short-covering rally has ended, and some models have seen a pullback and adjustment, with market prices fluctuating between increases and decreases.3、Price ForecastToday, prices in South China fell slightly, while those in East China declined, with overall transactions being weak. Trade merchants are finding it difficult to sell, and supply has increased significantly. It is expected that domestic ABS prices will continue to show a downward trend tomorrow. EVA：Low demand for foaming, focus of negotiations is relaxed.1 Today's SummaryThis week, the ex-factory price of EVA petrochemical plants remains stable.This week, most of the EVA petrochemical facilities are in stable production.2 Spot OverviewTable 1 Domestic EVA Price Summary (Unit: Yuan/Ton)Today's domestic EVA market atmosphere was lackluster. Traders in the market held divergent mindsets, leading to a somewhat chaotic offering situation. The demand for foaming applications advanced slowly, and some holders, driven by panic, offered discounts to promote transactions. Most deals were reached through negotiations, with a weak and wait-and-see atmosphere prevailing. By the close of the market, soft material was quoted at RMB 11,400-11,900/ton, and hard material was quoted at RMB 11,300-11,800/ton.3.Price ForecastIn the short term, the domestic EVA market fundamentals are expected to remain in a stalemate. Demand from the photovoltaic sector provides temporary positive support, with EVA manufacturers holding firm to stabilize the market. Mainstream agents follow suit to maintain stability, while downstream foam demand continues to follow rigid needs. The market transaction pace remains slow, and the supply-demand game persists. Industry players adopt a cautious approach to operations. Longzhong Information predicts that the domestic EVA market will experience weak and stable consolidation in the short term. Engineering materialsPC：The PC market is trending upwards with a strong consolidation.1、Spot OverviewTable 1: Summary of Domestic PC Prices (Unit: RMB/ton)Today's domestic PC market showed a slightly stronger trend. In the East China market, the mainstream intended price for domestic PC sources was between 12,200-12,650 yuan/ton, slightly stronger compared to the previous trading day. In the South China market, the mainstream intended price for domestic PC sources was between 12,400-13,000 yuan/ton, stable compared to the previous trading day. For foreign sources, prices of most goods remained stable. The mainstream price of Lotte 1100 in East China was 12,800-13,000 yuan/ton, stable compared to the previous trading day. The mainstream price of Covestro 2805 in South China was 15,150-15,300 yuan/ton, also stable compared to the previous trading day. The raw material Bisphenol A continued its upward trend, providing stronger support to the PC market. During the trading day, some offers continued to rise slightly, but downstream buyers became more cautious about chasing higher prices. New order transactions decreased compared to earlier in the week, and market participants started to adopt a wait-and-see attitude.Price PredictionIt is expected that the PC market will digest the increase in the near future. The specific reasons are as follows:Supply:Supply is abundant, and the seller's报价 is either stable or slightly fluctuating.Requirement:The overall downstream willingness to chase gains remains cautious.Cost: The slight increase in raw material bisphenol A provided support for the PC market. PET：The price of polyester bottle flakes has dropped by 10-20.1 Today's Summary①,华润 prices fluctuate slightly while other factories remain stable (Unit: Yuan per ton)②. Today, the domestic polyester bottle chip capacity utilization rate reached 72.61% (revised from yesterday's 72.61%).2 Spot OverviewTable 1 Domestic Polyester Bottle Chip Price Summary (Unit: Yuan/Ton)Based on the East China region, the spot price of polyester bottle chip (water bottle grade) today closed at 6065, down 15 from the previous working day, in line with the morning's expectations.Crude oil prices are correcting. Although news of maintenance at a major PTA plant has emerged, raw material prices continue to lack upward momentum. Most polyester bottle chip plants are holding steady, with partial price adjustments. Traders are mainly focused on offloading inventory, with April shipments reportedly transacted at 6,040–6,130 or at a discount of 30 to a premium of 50 against the 2505 contract. The basis has weakened slightly, with sporadic restocking for rigid demand and subdued trading activity. (Unit: RMB/ton)3、Price ForecastThe market is largely waiting for news on the U.S. imposing additional tariffs, leading to relatively stagnant trading. On the supply side, a major manufacturer has restarted a 700,000-ton facility, raising expectations for increased supply. Downstream demand remains focused on essential restocking, with low purchasing intention before the holidays. The polyester bottle chip market is experiencing weak fluctuations, and it is expected that the spot price for water bottle materials will operate in the range of 6000-6150 tomorrow. POM：Demand performance is weak, transactions continue through negotiation.1. Today's SummaryThe domestic material manufacturers have lowered their factory prices.2. Inadequate follow-up on demand orders, resulting in average sales performance.2Spot OverviewTable 1 Summary of Domestic POM Prices (Unit: Yuan per ton)Based on the Yuyao area, today the price of Yun Tianhua M90 is 13,500 yuan/ton, with limited price fluctuations.Today, the POM market saw a downward trend in its center of gravity. Shipments were slow across various regions, increasing the pressure on petrochemical plants to offload inventory. Some POM manufacturers further reduced their ex-factory prices, dampening market sentiment. Traders lacked confidence in their operations, leading to a continued decline in mainstream offers by 100-800 yuan/ton. Downstream users remained cautious and观望情绪主导, resulting in subdued trading activity. The mainstream报价区间 ranged from 9,800 to 13,700 yuan/ton.3、Price prediction The shipment situation in various regions has not improved significantly during the week. The total inventory of POM petrochemical plants will continue to rise. In addition, some manufacturers have lowered their ex-factory prices for the second time, making it difficult for the market sentiment to be supported. Traders are less interested in operations, and the focus of quotations will continue to fall. End users are mostly cautious and观望ing, with sporadic actual transactions. It is expected that the domestic POM market will fall narrowly in the short term. PBT：The PBT market shows a weak and fluctuating trend.1 Today's Summary①PBT manufacturers' quotations remain stable.This week, the supply side saw the restart of PBT operations at the Fujian Meizhou Bay facility.③ China's PBT industry production reached 23,075 tons this week, with a capacity utilization rate of 54.32%, an increase of 4.47% compared to last week. The domestic average gross profit for PBT in China this week was -498 yuan per ton, a decrease of 97 yuan per ton compared to last week.2 Spot OverviewTable 1: Summary of Domestic PBT Prices (Unit: RMB/ton)Translate the above content from Chinese to English and output the translation result directly without any explanationThe East China region is the benchmark.Today, the mainstream price for medium to low viscosity PBT resin is between 7800-8200 yuan/ton.Decreased by 50 yuan/ton compared to yesterday。Today, the PBT market is weak and falling, while the PTA market remains steady. The BDO market is operating with观望 (wait-and-see attitude). With general cost support, the PBT supply side continues to focus on sales, and there are reports of lower prices in the market, causing the market's focus to weaken and fall. According to Longzhong Information statistics, the price range for medium to low viscosity PBT pure resin in the East China market is between 7800-8200 yuan per ton.3. Price PredictionIt is expected that the PBT market will remain weak and观望 (note: 'watchful' or 'cautious'). On the cost side, there is an expectation of reduced load in both supply and demand for PTA, with poor purchasing enthusiasm from downstream buyers, leading to a low overall valuation of the industry chain. However, cost support remains, and the market lacks a sustained driving force. In the short term, the domestic PTA spot market will maintain a volatile pattern. BDO currently has decent support on the supply side, with downstream demand following at a basic pace, but the cost transmission within the industry chain is not smooth, suppressing the movement of raw materials, and the market performance is weak. With average cost support, the PBT market sees an increase in the mentality of shipping out goods, and there may be an increase in low-priced sources in the market, causing the market focus to run weakly. Therefore, it is expected that the medium and low viscosity PBT resin in the East China market will be priced at 7800-8100 yuan/ton tomorrow. PA6：Rigid报价 firm for slice manufacturers as PA6 market prices increase1 Today's Summary①. Sinopec's weekly settlement price for caprolactam was 10,280 yuan/ton (six-month interest-free acceptance), a decrease of 100 yuan/ton compared to last week.② Sinopec pure benzene price at refineries in East China and South China increased by 150 yuan per ton, now executing at 6750 yuan per ton, with prices effective from April 1st.2 Spot OverviewTable 1 Summary of Domestic Polyamide 6 Prices (Unit: RMB/ton)Today, the price of conventional spinning polyamide 6 chips has risen. The supply of raw material caprolactam has decreased, and companies are holding firm on their quotations. The cost support for chips has strengthened, and polymerization companies, with thin profit margins, have raised the ex-factory prices of chips. However, downstream production companies are cautiously observing the market, replenishing stocks at appropriate prices, resulting in limited transactions. Market negotiations are based on actual orders. In East China, conventional spinning PA6 is priced at 10,650-10,950 yuan/ton cash on short delivery, while high-speed spinning spot is priced at 11,100-11,600 yuan/ton on acceptance delivery. In Chaohu, the price is 9,800-9,900 yuan/ton cash on self-pickup.3、Price ForecastFrom the cost perspective, the supply of raw material caprolactam has decreased, leading to a relatively firm price, and the pressure on polymerization costs has increased. From the supply and demand perspective, Zhejiang Fangyuan and Fangming are undergoing maintenance shutdowns, and some enterprises are reducing production, resulting in decreased supply. Downstream businesses are primarily restocking on demand, and some polymerization companies have reduced inventory pressure. It is expected that the nylon 6 market will operate with a slight preference for consolidation in the near term, closely monitoring downstream demand and manufacturers' pricing dynamics. PMMA： The upstream and downstream sectors continue to game, and the market maintains a stable trend.1. Today's summary① Today's factory prices remain stable.2. The domestic utilization rate of PMMA particles today is 64%.2 Spot OverviewTable 1 Summary of Domestic PMMA Particle Prices (Unit: CNY/ton)PMMA particle prices in East China closed at 16,700 yuan per ton today, unchanged from yesterday, below early expectations.Today, the PMMA particle market remained stable, with a predominant wait-and-see attitude. Suppliers showed no clear intention for deep price cuts, maintaining steady pricing sentiment. Downstream demand stayed unchanged, with procurement continuing at a rigid pace, while actual transaction volumes saw insufficient follow-up.3. Price PredictionThe short-term PMMA particle market price is stable, with sellers maintaining a steady mindset and limited room for negotiation. At the beginning of the month, there is insufficient market news and we still need to wait for further clarification in the market. In summary, with ongoing games between upstream and downstream, the short-term PMMA particle market is expected to maintain a steady trend, with attention on the shipping rhythm and receiving dynamics. PA66Downstream purchases at high prices are cautious, and the market is consolidating weakly.1 Today's summary① On April 1, market attention shifted from production sanctions to U.S. tariff policies, raising concerns about the drag on demand prospects, leading to a decline in international oil prices. NYMEX crude oil futures contract for May fell by $0.28 per barrel to $71.20, a decrease of -0.39%; ICE Brent crude oil futures contract for June, rolling over to July, fell by $0.28 per barrel to $74.49, a decrease of -0.37%. China's INE crude oil futures main contract for May rose by 11.6 to 549 yuan per barrel, with overnight trading rising by 4.3 to 553.3 yuan per barrel.As of today, the domestic PA66 capacity utilization rate is 57%, with a daily output of approximately 2,200 tons. Under pressure from costs and demand, domestic PA66 enterprises have reduced their capacity utilization rates, and the demand side is average, resulting in a relatively abundant supply of goods in the domestic PA66 industry.Invista (China) Investment Co., Ltd. announced that from April 1, 2025, at 7:00 AM, the spot trading price of hexamethylenediamine will be set at 21,300 RMB/ton, remaining stable compared to the March price.2 Spot Market OverviewTable 1 Domestic PA66 Price Summary (Unit: RMB/ton)Referring to the Yuyao market in the East China region, the EPR27 price today is referenced at RMB 16,700-16,900 per ton, unchanged from yesterday's price.Raw material prices are fluctuating, providing limited cost support. Downstream buyers are purchasing as needed, and market supply is ample. Aggregation companies have implemented concentrated production reduction plans, and the market is temporarily stable. 3. Price ForecastingDemand shows no significant recovery, with downstream sectors purchasing as needed. Under cost pressures, polymerization companies have a strong inclination to reduce production. It is expected that the domestic PA66 market will consolidate in the short term.

Details of changes in domestic PP maintenance units: the second line of Zhongjing Petrochemical's Phase II (600,000 tons/year) PP unit has restarted. The daily production ratio of raffia decreased by 2.08% to 25.41%, mainly due to the switch to other products in the second line of Sinochem Quanzhou. ③、 。 2 Current Spot Situation Polypropylene priceSummary Table (Unit: Yuan/Ton) market 4 Month 1 Day 1 4 February 2nd Rise and fall value 涨跌幅 Fluctuation in price上涨/下跌的幅度 Nationwide 7337 7341 +4 0.05% East China 7361 7369 +8 0.11% North China 7295 7301 +6 0.08% South China 7419 7422 +3 0.04% Central China 7285 7286 +1 0.01% Southwest 7313 7306 -7 -0.10% northwest 7172 7174 +2 0.03% Key Downstream BOPP 8350 8350 0 0.00% Data source:Longzhong Information Start withAs of today, the closing price for polypropylene fiber in the East China region was 7,369 yuan per ton, an increase of 8 yuan per ton from yesterday, in line with the morning's expectations. Futures are trading in a range with a slight upward bias. Today, polypropylene prices are mainly consolidating. The implementation of tariff policies has boosted the market, and the red trend on the futures market is supporting spot quotes. However, terminal demand remains weak, causing spot prices to fluctuate. Market traders are mostly operating according to the market, with actual transactions being negotiated. By midday, the mainstream price range for拉丝in East China was between 7,320 to 7,450 yuan per ton. 。 Figure 1: Domestic Polypropylene Price Trend (Unit: Yuan/Ton) Figure 2 Domestic polypropylene price trend chart by region (Unit: Yuan per ton)                                                                                   Data source: Longzhong InformationData Source: Longzhong Information 3 Spot-futures basis In terms of basis, today the basis in the North China region is -57 yuan/ton, down 14 yuan/ton from yesterday; the polypropylene basis in the East China region is 11 yuan/ton, down 12 yuan/ton from yesterday.

Figure 5: Trend Chart of Domestic Polypropylene Capacity Utilization Rate Figure 6 Domestic polypropylene profit price trend chart (Unit: yuan/ton) Data source: Longzhong InformationData source: Longzhong Information 5 Market sentiment Recently, international oil prices have been relatively strong, with support for PP at the bottom. The futures market has shown a firm performance, and spot prices have slightly increased. Downstream demand remains mostly cautious, with some entering the market for essential purchases, but there is limited acceptance of high prices, providing insufficient support for prices. Traders are primarily cautious and are letting go of inventory based on market conditions. 6 Affected by the US tariff policy, international oil prices may be dragged down due to concerns over demand prospects, which is expected to provide limited support for PP (polypropylene) from the cost side. In terms of demand, downstream purchases mainly maintain their minimum needs and tend to buy at lower prices, which does not significantly boost the market. On the supply side, there is no new increase in production capacity in the short term, coupled with the relatively concentrated maintenance shutdowns of production enterprises in the short term, keeping the supply pressure manageable. It is expected that the polypropylene market tomorrow may fluctuate within a range, with the mainstream price of East China拉丝 (a specific type of polypropylene product)mainly between 7,300-7,450 yuan/ton. Note: "拉丝" specifically refers to a type of polypropylene product used for fiber or filament production, but it's typically translated or left as-is in English technical contexts. If a more generalized translation is preferred, it could be translated as "polypropylene fiber/filament," but here it's kept in its original form given the context. 。 7 Table 2: Summary of Polypropylene Related Product Prices (Unit: RMB/ton) Market 4 It is already in English.

The offers remain stable, in line with this morning's expectations. Currently, the operating load of recycling manufacturers is not high, but compared to demand, spot supply is still adequate. The supply of raw materials is limited, and prices remain elevated. Affected by this, manufacturers are reluctant to sell at low prices, and actual transactions continue to be negotiated. Figure 1: Domestic Recycling 2024-2025 PE market price trend chart (Yuan/ton)   3 Production dynamics This week, the capacity utilization rate of the domestic recycled polyethylene market remained at a low level of fluctuation. Currently, the operating rate in the market is 25.7%, an increase of 0.2 percentage points compared to last week. Although it is the peak season, downstream manufacturers have not received many new orders. Coupled with the relatively weak fluctuations in the new material market, downstream buyers continue to purchase recycled materials on a needs basis with small orders. The market transaction pace is slow, and recycled enterprises maintain a cautious attitude, mostly producing flexibly according to orders from old customers. Overall, the operating rate of the recycled PE market this week did not change much. Figure 2 Domestic Recycled PE Capacity Utilization Trend Chart   4 Price prediction The再生PE market continues with its current quotes, and players are adopting a cautious approach. Seasonal peak demand is driving downstream enterprises to maintain their essential purchasing rhythms; however, the release of terminal product orders remains slow, indicating that demand support at this stage is somewhat weak. Regenerated enterprises are scheduling production flexibly based on orders, with spot inventory levels staying within reasonable ranges. Most holders are maintaining an active sales strategy. The difficulty in collecting raw materials has not diminished, leaving limited room for negotiation, and cost support persists. Overall, the market is expected to remain in a narrow range adjustment in the short term, with limited price fluctuation space. 5 , Relevant product information PE Market: Today, the domestic polyethylene spot market prices are mixed. The HDPE spot market price has slightly adjusted by 2-6 yuan/ton. Some equipment maintenance and production changes have led to a slight tightening of supply, but overall market demand is limited, and the end-users have a clear resistance to high-priced resources, resulting in mainly minor price fluctuations. The LDPE spot market price has slightly increased by 2 yuan/ton, with relatively stable supply and a slight improvement in some downstream demand, leading to a small price rise in the market. The LLDPE spot market price has slightly decreased by 7 yuan/ton, with overall supply pressure remaining high and no significant improvement in downstream demand. Market participants lack confidence and maintain a proactive selling strategy, causing prices to continue to decline slightly.

Supply pressure remains, so most grades are still priced relatively low. In the short term, with expectations of new capacity from Exxon and Inner Mongolia Baofeng coming online, the terminal inquiry price intentions are lower, and traders may have to passively offer discounts. However, strong support from the cost side, along with increased low-end transactions, provides confidence to the market, and prices are likely to remain in a low and narrow fluctuation range. 7 , related product information Crude oil market: In the short term, the main trading logic of the international crude oil market has shifted. The upside comes from heightened U.S. sanctions on Iran and geopolitical instability, while the downside stems from Trump's tariff policies dampening demand expectations, OPEC+'s modest production increase, and a strong U.S. dollar. Today, some of Trump's previously announced tariff policies will take effect, with potential new tariffs to be announced, keeping global economic and demand pressures elevated. International crude oil prices are expected to trend downward today. 8 Data Calendar Table 3 Overview of Domestic Polyethylene Data (Unit: 10,000 Tons) Data Release Date Last period's data This period's trend forecast PE Total inventory of production enterprises (million tons) Wednesday 5:00 PM 50.47 ↘ PE Social sample warehouse inventory Tuesday 17:00 PM -2.99 ↘ PE Weekly production (10,000 tons) Thursday 5:00 PM 61.64 ↗ PE Maintenance Impact Volume (10,000 tons) Thursday 5:00 PM 10.51 ↘ PE Weekly capacity utilization rate Thursday 17:00PM 82.32% ↗ PE Downstream industry capacity utilization Thursday at 5:00 PM +2.29% ↗ PE Mindset Research Thursday 12:00 AM -3.96% ↗ Data source: Longzhong Information Note: 1 ，↓↑ are considered as significant fluctuations, highlighting data dimensions with changes exceeding 3%. 2 Consider ↗↘ as narrow fluctuations, highlighting data with price changes within 0-3%. 3 The above data is updated every Thursday.

Since 2025, the domestic polycarbonate (PC) market has experienced significant price fluctuations under the dual pressure of supply and demand imbalance and cost reduction.. Especially inIn mid-March 2025, the decline in the PC market further widened, hitting a new low since the second half of 2020. Taking Huadong Lihua Yi WY-111BR as an example, the average price in the first quarter was 12,396 yuan/ton, a decrease of 3.28% quarter-on-quarter and 10.02% year-on-year.One, Supply and Demand Imbalance: High Capacity Utilization Rates and Weak Downstream DemandIn 2025, the domestic PC industry's capacity utilization rate continued to operate at a high level, with a substantial capacity base and production reaching new highs. As of March 2025, the total capacity of the domestic PC industry remained at 3.81 million tons per year, and the industry's average operating rate rose to 84.75% in March.The weekly output is approaching.70,000 tons, the market supply is highly abundant. The operating load of PC has also reached the highest point in nearly five years. In addition, the 180,000 tons/year PC facility of Zhangzhou Chi Mei is scheduled to start operating in March, further increasing the total domestic PC production capacity and supply.However, in sharp contrast to the strong growth on the supply side, downstream demand appears weak. Before the Spring Festival, apart from the modified industry where orders and purchases were relatively strong, other industries mostly stopped work and took holidays early. After the Spring Festival holiday, the demand from major consumer industries started to recover more slowly than expected.In March, there is still no improvement. The new order volume from downstream terminal factories is limited, leading to a noticeable slowdown in inventory consumption, which mainly relies on consuming previous stock levels. The operating rate of small and medium-sized factories is only 0-60%. Against the backdrop of abundant supply, the limited rigid demand from downstream buyers is more passive and cautious, resulting in poor market transactions and increasing pressure of imbalance between production and sales in the industry.II. Cost decline: Raw material prices have dropped significantly.Bisphenol in the first quarter Market A overall showed a downward trend from a high position. In March, as international crude oil prices plummeted, energy chemical product prices continued to decline. The upstream of the industry chain, pure benzene, started a rapid price drop mode, and raw materials such as phenol and bisphenol A also decreased to varying degrees following the cost, weakening the cost support for PC. In March, the average price of bisphenol A in East China was 9,350 yuan/ton, a year-on-year decrease of 1.98%, further weakening the cost support for the PC industry. The industry's theoretical gross profit once fell into a loss. In late March, PC factories gradually became cautious about low selling intentions. As the price of bisphenol A fell, the PC gross profit level gradually recovered.Future Market Outlook: Weak Consolidation as the Main ThemeFrom the supply side, despite Luxi ChemicalOne production line of the PC facility remains shut down, but the overall operations of other domestic PC facilities remain stable.
