Introduction: The "Golden Duo" of Plastic Processing In plastic processing, lubricants are indispensable key additives. Acting like a “lubricant” for plastic melts, they effectively reduce frictional resistance between molecules and between the mater

Silicon dioxide (SiO₂) is the most widely distributed inorganic compound in the Earth's crust, existing in natural forms such as quartz and diatomaceous earth, and can also be artificially synthesized as an amorphous powder.Strong chemical stability,

Today, amid the modernization of agriculture, agricultural plastic mulch is known as the “second skin” of crops. By raising soil temperature, retaining soil moisture, and suppressing weed growth, it has made great contributions to stable and inc

1 引言PC热分解区间450～550℃，受热发生Fries重排生成酚羟基与小分子裂解产物，释放苯系可燃挥发物，燃烧伴随大量灼热熔滴是火灾扩散的关键诱因。阻燃改性主要分为添加型阻燃（工业化主流）与反应型共聚阻燃（高端特种PC）两类：添加型工艺简单、成本可控、适配现有挤出改性生产线；反应型通过化学键将阻燃元素接入PC分子链，无助剂析出、耐水解与热稳定性更优，但聚合工艺复杂、生产成本偏高。全球环保管控趋严，欧盟REACH2.0、中国RoHS3.0全面限制多溴二苯醚、PFAS类防滴落助剂使用，无卤低烟、

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

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

Market Overview: On June 17, PA66 market prices remained stable, with the market average at RMB 18,750/ton, unchanged from the previous working day. Feedstock adipic acid prices were stable, while hexamethylenediamine prices fluctuated within a range

I. Opening: Where Does Anxiety Come From? After Orion’s Qingdao plant went into production and Yongdong’s patents were made public, many local pyrolysis plant owners could no longer sit still. “Foreign giants have come in, and traditional carbon blac
