欧利隆刚官宣100% TPO量产，永东股份就抛出裂解油专利——两大巨头，同一赛道，两种打法。 一、开篇：前后脚的信号 2026年6月初，欧利昂（Orion）青岛工厂投产的消息还没凉，另一则消息悄悄出现： 国内炭黑龙头永东股份，一项关于“利用再生资源制备炭黑”的发明专利被公开。 两件事只隔几天，释放同一个信号： 传统炭黑巨头，正在集体转向循环原料。 二、专利速览：永东在做什么？ 一句话概括：在传统煤焦油路线上，掺入废轮胎裂解油，做“混合版”再生炭黑。   三、三个关键细节，看懂永东路线 1. 混

无论在常温还是高温条件下，滑石粉作为无机填料用于塑料改性中都能起到重要作用，已成为塑料工业中不可或缺的改性助剂。添加滑石粉可以提高塑料的表面硬度、冲击强度、拉伸强度、弯曲模量、耐磨及阻燃性能等。 1、PTFE的改性 聚四氟乙烯（PTFE）树脂具有优异的耐高低温、耐老化、耐腐蚀、高绝缘等性能，但由于其尺寸稳定性与导热性能差、蠕变大且硬度低，尤其在载荷下易磨损，限制了其在机械承载、摩擦磨损和密封润滑等领域的应用，故需要对其进行填充改性。据报道，加入滑石粉能显著增加PTFE复合材料的硬度，

Under the trend of lightweight engineering plastics, nylon materials are widely used in automotive components, new energy parts, electronics, industrial ties, and pipes and fittings due to their excellent mechanical properties, wear resistance, and c

Talc is a hydrated silicate with the chemical formula 3MgO·4SiO2·H2O. Its crystalline forms can be flaky, leaf-like, needle-like, and massive. The structure of pure talc consists of a layer of brucite (magnesium hydroxide, MgO·H2O) sandwiched between

The bio-based aromatic materials team at the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, led by Senior Engineer Zhang Yajie, has published in *Bioresource Technology* the results of more than a decade of R&a

PET and BOPET films used outdoors are often exposed to the combined effects of ultraviolet light, heat, oxygen, water vapor, and mechanical stress. Good performance when the material first leaves the factory does not necessarily mean that it will rem

The application of modified PA6 in energy storage connectors lies in enhancing the material through reinforcement, flame retardancy, and other modifications to meet stringent requirements in terms of mechanical, electrical, and safety performance. Th

PBT is a crystalline linear saturated polyester produced by the polycondensation of terephthalic acid (PTA) or dimethyl terephthalate (DMT) with 1,4-butanediol (BDO). It has excellent mechanical properties, and its symmetrical molecular structure ena

Nylon is a common engineering plastic.It has long been widely integrated into our daily lives. The moment you wake up in the morning and brush your teeth.，The nylon bristles of the toothbrush have quietly completed an intim

The low-altitude economy has now become a booming sector. Drones, once regarded merely as high-end toys, are now being widely deployed in areas such as agricultural and forestry plant protection, terrain surveying, urban logistics and delivery, and e

PEEK fiber, fully known as polyether ether ketone fiber, is a high-performance specialty fiber made from polyether ether ketone (PEEK) resin through a melt spinning process. Its core advantage lies in its outstanding overall performance, especially i

Aluminum hypophosphite is currently a high-cost-performance "top performer" in the halogen-free flame retardant field for nylon and elastomers. It does not simply replace traditional flame retardants, but rather works in combination with mainstream f

As polymer materials technology continues to evolve and masterbatch applications expand into high-end fields, performance standards are rising accordingly. Among these, the uniform dispersion of fillers, as a core indicator for measuring the technica

Under the trend toward lightweight engineering plastics, nylon materials, owing to their excellent mechanical properties, wear resistance, and chemical corrosion resistance, are widely used in automotive components, new energy accessories, electrical

This paper systematically reviews the latest research progress in modified polyether ether ketone (PEEK) composites, focusing on three major directions: blend modification, inorganic filler modification, and modificat

In the world of nylon blending modification, coupling agents play a crucial role as "molecular bridges." They act like an outstanding "interface engineer."The core function is to solve interfacial incompatibility problems between different materials

Add hydrotalcite to the flame-retardant nylon formulation.The core function is to serve as an efficient and environmentally friendly multifunctional synergist. It is not a primary flame retardant in itself, but rather enhances or improves the perform

Flame retardants are the second largest plastic additive after plasticizers. They can be classified into two main categories based on chemical structure: organic flame retardants and inorganic flame retardants. According to the type of elements, they

In the modified plastics industry, those working on reinforcement and filling modification of polyolefins are probably spending every day going head-to-head with all kinds of tough performance requirements from downstream customers.The flexural mod

From 2024 to 2026, flame-retardant modification technology for PA66 is undergoing a critical transition from “single-function additives” to “multifunctional synergistic, intelligent response” systems. The core strategy of current research is to addre
