1.1 The market for special engineering plastics is expected to continue to achieve rapid growth
Plastic is a type of synthetic polymer material with plasticity, which can be divided into general plastics, engineering plastics, and special engineering plastics. General plastics are mainly bulk plastics with large production and wide applications, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylic butadiene styrene (ABS), etc. Engineering plastics are plastics that can withstand certain external forces, have good mechanical properties and dimensional stability, and maintain their excellent performance at high and low temperatures. They can be used as engineering structural components, including polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), thermoplastic polyester (PBT), etc.
Special engineering plastics refer to a type of engineering plastic with high comprehensive performance and long-term use temperature above 150 ℃, including polyphenylene sulfide (PPS), polyimide (PI), polyether ether ketone (PEEK), liquid crystal polymer (LCP), and polysulfone (PSF). Among them, special engineering plastics have special properties such as high temperature resistance, high strength, and fatigue resistance compared to ordinary engineering plastics. 【 Learn more about industry knowledge such as' plastics', 'engineering plastics', and' modified plastics', massive material super property tables, numerous material selection cases, cost reduction and efficiency improvement solutions, welcome to enter the 'Plastic Library Network' to solve!!!! 】, creep resistance, and chemical resistance. They are widely used in many fields such as aerospace, military industry, electronic appliances, automobiles, home appliances, kitchen and bathroom, transportation, medical equipment and machinery manufacturing, precision equipment, etc. 】. Compared to engineering plastics, special engineering plastics have better performance, stricter technical standards, and higher added value. As a new polymer material, special engineering plastics are the third generation of plastics developed after general plastics and engineering plastics. They have the advantages of heat resistance, insulation, corrosion resistance, and high mechanical strength. With the arrival of the era of 5G communication, semiconductor, and material upgrading in the medical industry, the replacement speed of special engineering plastics for traditional materials is further accelerating.
