In the pursuit of designing new lightweight, flexible, and efficient heat dissipating materials for modern devices, the research team led by the University of Massachusetts Amherst has made a groundbreaking discovery: defects can also create advantages. This research, published in "Science Advances," demonstrates through experiments and theory that polymer composite materials with defective thermal conductive fillers can increase thermal conductivity by 160% compared to similar materials using perfect fillers, completely overturning the traditional perception that "defects must damage performance." Key breakthroughs Disruptive discovery: Defective graphene oxide filler (thermal conductivity only 66.29 W/mK) incorporated into polymer outperforms perfect graphite filler (292.55 W/mK) by 160% Mechanism Innovation: The formation of defects on rough surfaces enhances the vibrational coupling at the polymer/filler interface, reducing thermal contact resistance. Application potential: Opens new pathways for developing ultra-high thermal conductivity polymers, which can solve the heat dissipation problems of devices such as microchips, flexible electronics, and soft robots. Traditional Dilemma: The Limitations of Perfect Packing Materials Polymers, with their lightweight, insulating, and flexible properties, have become core materials in modern technology. However, their **inherently low thermal conductivity (0.1-0.5 W/mK)** has led to serious overheating issues in devices. The academic community has long sought to enhance thermal conductivity by incorporating metal, ceramic, or carbon-based fillers, but the actual results have fallen far short of theoretical predictions. Diamond filler case: Theoretical thermal conductivity should reach 800 W/mK with a 40% loading, but the actual value is only around 10 W/mK. Key limiting factors: filler agglomeration, interfacial contact thermal resistance, low thermal conductivity of polymer matrix Defect Engineering: Turning Disadvantages into Advantages The research team revealed through multi-scale experimental-theoretical approaches that defects play a positive role: Material Design Control group: 5% volume fraction of perfect graphite (292.55 W/mK) Experimental group: 5% volume fraction of defective graphene oxide (66.29 W/mK) Disruptive Outcome The thermal conductivity of polymer composites with defective fillers is significantly higher. Mechanism Analysis: ▶️ Defects causing rough surfaces prevent polymer chains from packing tightly ▶️ Enhanced interfacial vibrational coupling (improved phonon matching) ▶️ Construction of efficient heat flow channels, reducing interfacial thermal resistance Technical Validation System The study employs a four-in-one cross-validation method. Thermal Transport Measurement: Precise Quantification of Material Performance Enhancement Neutron Scattering: Resolving Atomic Scale Vibrational Modes Quantum Mechanics Modeling: Revealing Electron-Level Interactions Molecular Dynamics Simulation: Tracing the Path of Heat Energy Transfer Application Prospects and Significance This discovery provides a novel approach for the design of functionalized polymers. Next-generation electronic devices: Addressing heat dissipation bottlenecks in 5G chips, Micro LED, and more Flexible electronics: Development of high thermal conductivity elastomers for wearable devices Energy Sector: Enhancing the Safety and Efficiency of Battery Thermal Management Systems Aerospace: Manufacturing Lightweight and Efficient Thermal Protection Materials Professor Yanfei Xu, the head of the research team, emphasized: "Defect engineering will become a crucial direction in future materials science. By precisely regulating interface properties, we have the potential to break through the theoretical limits of polymer thermal conductivity."

On March 27, BASF announced the commissioning of the world's first commercial Loopamid plant. The production facility located at the Caojing site in Shanghai, China, has an annual capacity of 500 metric tons, marking an important step toward sustainable product supply in the textile industry. "The launch of this facility once again demonstrates BASF's innovative strength," said Dr. Stephan Kothrade, Member of the Board of Executive Directors and Chief Technology Officer of BASF. "As an integral part of our strategy, we use chemistry to develop solutions that address the biggest challenges of our time. Loopamid transforms textile waste into valuable resources, helping to conserve raw materials and close the loop in the textile cycle." Loopamid is a recycled polyamide 6 entirely based on textile waste. The new production facility supports the textile industry's growing demand for sustainable polyamide 6 fibers. "I am proud of our team, who have worked with great enthusiasm and dedication to bring loopamid to commercialization," said Ramkumar Dhruva, President of BASF's Monomers business unit. "The technology behind loopamid allows for textile-to-textile recycling of polyamide 6 in various fabric blends, including those mixed with elastic fibers. I believe loopamid not only makes a significant contribution to the textile circular economy but also helps our customers achieve their sustainability goals." Factory and Loopamid product GRS certification The new Loopamid factory integrated into the Shanghai Caojing Polyamide-6 plant. The production quantities of both the factory and Loopamid are in accordance with the Global Recycle Standard (GRS). This certification assures consumers and textile manufacturers that Loopamid is made from recycled materials and that the production process meets specific environmental and social standards. Additionally, the first yarn manufacturers are successfully using Loopamid. Industrial and consumer textile waste As the foundation of loopamid To produce Loopamid in the new factory, BASF is currently utilizing industrial textile waste from the textile production process and will gradually increase the share of post-consumer waste. These materials include cut edges, defective cut edges, leftovers, and other production textile waste from the textile industry. These materials are collected and provided to BASF by customers and partners. Discarded clothing made from polyamide 6 and other textile products can also be used for Loopamid production. All these waste materials are difficult to recycle because they typically consist of mixtures of different fibers, materials, dyes, and additives. Furthermore, for post-consumer waste recycling, buttons, zippers, and accessories must be removed in advance. BASF collaborates closely with partners and customers to accelerate the development of collection and sorting systems. About Loopamid BASF has developed an innovative solution through Loopamid to enhance the circularity of the fashion industry and recycle polyamide 6 textile waste. Thanks to its ability to tolerate all fabric mixtures including PA6 and elastane fibers, the technology behind Loopamid allows for textile-to-textile recycling of both post-industrial and post-consumer textile waste. Fibers and materials can be recycled multiple times, while maintaining material properties equivalent to those of traditional virgin polyamides.

On April 4, the State Administration for Market Regulation of China announced that DuPont China Holding Co., Ltd. is being investigated for suspected violations of the Anti-Monopoly Law of the People's Republic of China. The market regulation authority has initiated a formal investigation against DuPont China Holding Co., Ltd. in accordance with the law. The specific reasons are still unknown, but against the backdrop of China's strong emphasis on foreign investment, the investigation into DuPont China may highlight China's determination to create a fairer market environment or have profound effects on the operating models of multinational companies in China. It is reported that DuPont established its office in Beijing in 1984 and set up its first wholly foreign-owned enterprise, DuPont China Group Limited, in Shenzhen in 1988, becoming the first wholly foreign-owned investment company approved by the Chinese government. It is reported that by 2025, DuPont will have more than 40 wholly-owned and joint ventures in China, covering the entire industrial chain from basic chemical materials to high-end automotive and electronic solutions. Some of the core brands mainly include: Kevlar®: para-aramid fiber, mainly used for protective equipment, industrial and technological applications, and sports equipment.

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 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.

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.

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.

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.

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. In April, the PC facilities of Pingmei Shenma, Cangzhou Dadi, and Sino-Saudi Tianjin all have scheduled maintenance outages planned, leading to a temporary reduction in industry-wide capacity utilization to around 75%. As market supply decreases, sellers may maintain their price expectations, which could potentially lead to a bottoming out of the PC market. However, downstream terminal demand is unlikely to improve significantly in the short term, exacerbating the supply-demand imbalance. Weak demand limits the upward movement of quotations, making it difficult for merchants to maintain firm prices, leaving room for potential discounting to promote transactions. Author:Zhao Hongyan，Specialized Plastic Vision Market Research Expert
