Engineering Plastics
Generally speaking, it can bear a certain external force, has good mechanical properties and high and low temperature resistance, and has good dimensional stability. It can be used as engineering plastics, such as polyamide and polysulfone. In engineering plastics, it is divided into two categories: general engineering plastics and special engineering plastics. Engineering plastics can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in electrical and electronic, automotive, construction, office equipment, machinery, aerospace and other industries. It has become an international trend to replace steel and plastic.
General engineering plastics include: polyamide, polyoxymethylene, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra high molecular weight polyethylene, methylpentene polymer, vinyl alcohol copolymer and the like.
Special engineering plastics also have a cross-linked type of non-crosslinking type. Crosslinking types include polyaminobismaleamide, polytriazine, crosslinked polyimide, heat resistant epoxy tree, and the like. Non-crosslinked types include polysulfone, polyethersulfone, polyphenylene sulfide, polyimide, polyetheretherketone (PEEK), and the like.
