Classification of Engineering Plastics
Engineering plastics can be divided into two categories: general engineering plastics and special engineering plastics. The main varieties of the former are five general engineering plastics: polyamide, polycarbonate, polyformaldehyde, modified polyphenylene ether, and thermoplastic polyester; the latter mainly refers to engineering plastics with a heat resistance of more than 150 ° C. The main varieties are polyimide , Polyphenylene sulfide, polysulfones, aromatic polyamides, polyarylates, polyphenylene esters, polyaryletherketones, liquid crystal polymers, and fluororesins.
