Engineering Plastics is a plastic that can be used as a material and substitute for metal parts. Engineering Plastics has excellent comprehensive performance, rigid, small creep, high mechanical strength, good heat resistance, good electrical insulation, can be used in the more stringent chemical and physical environment for long-term, can substitute metal as engineering structure material use, but the price is more expensive, the production is smaller.
Engineering Plastics can be divided into general Engineering Plastics and special Engineering Plastics. The former main varieties have polyamide, polycarbonate, pom, modified polyphenylene ether and thermoplastic polyester five general engineering plastics; the latter mainly refers to heat resistance up to 150 ℃ above the engineering plastics, the main varieties have polyimide, Polyphenylene sulfide, Polysulfone class, aromatic polyamide, poly-aromatic ester, poly-benzene ester, polyether ketone, liquid crystal polymer and fluorine resin.
