PPS plastics have many electronic products and plastic products in the automotive industry, but there are white, hard and fragile plastic products. They fall to the ground with the sound of metal, and the light transmittance is second only to that of plexiglass. The waterproof and chemical stability of coloring are the same. Generally, it refers to the ability to accept certain external forces, with outstanding mechanical functions and high and low temperature resistance, Plastic raw materials with good scale stability have good comprehensive functions, such as large rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation. It can be used in harsh chemical and physical environment for a long time. PPS plastic can replace metal as engineering structural material, but its price is relatively high and its output is small. In the modified plastic raw materials, some are classified according to the electrical properties, and some are classified according to the production methods. How many are classified according to the production methods? Let's see. PPS plastics manufacturers can be divided into structural modified plastic materials and composite modified plastic raw materials according to the production methods of modified plastic raw materials. Structural modified plastic raw material, also known as intrinsic modified plastic raw material, refers to the conductive plastic itself or chemically modified.
PPS plastic structure polymer conductive materials mainly include: metal chelates: such as polyketo phthalocyanine; charge moving polymer complexes: such as polycation, CQ complex. Talc is often used to fill polypropylene. Talc powder has the characteristics of lamellar structure, so the fine talc powder can be used as reinforcing filler for polypropylene. The addition of superfine talcum powder masterbatch in the modification system of PPS plastics can not only significantly improve the rigidity, surface hardness, thermal creep resistance, electrical insulation, scale stability of polypropylene products, but also improve the impact strength of polypropylene. Adding a small amount of talcum powder in polypropylene can also play a role of nucleating agent, improve the crystallinity of polypropylene, and then improve the mechanical functions of polypropylene. Because the crystallization of polypropylene is improved and the grain size is refined, the transparency of polypropylene is improved. Polypropylene composites filled with 20% and 40% ultrafine talc powder can significantly improve the rigidity and creep resistance of polypropylene at room and high temperature.
For example, PPS has the advantages of low density, good transparency, high tensile strength, high hardness, good heat resistance, but its impact function is poor, and its stress cracking resistance is not good. If blended with HDPE, it can adhere to the original advantages of PP, and make the blends have the advantages of impact resistance, stress cracking resistance and low temperature resistance. Generally speaking, the flame retardant skills of polymers can be divided into two types: increasing type and reactive type. Various production line parts, semiconductor liquid crystal manufacturing equipment parts, inspection equipment parts, manufacturing fixture, atomic energy related parts, electronic components, various precision machine parts, food processing line related parts, chemical machinery equipment related parts, welding machine related parts, gold plating machine related parts, metal surface treatment related parts Parts, insulation parts, etc. PPS plastic is a new type of light and high strength engineering structural material. Because of its light weight, low price and easy recovery and reuse, with the development of automobile industry, the use of PPS in automobile is developing rapidly.
