What material is polyphenylene sulfide?

Polyphenylene sulfide is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability and excellent electrical properties. Widely used in electronics, automobiles, machinery, chemical industry and other fields.

Polyphenylene sulfide, also known as polyphenylene sulfide, is a thermoplastic resin with phenylthio group in its main chain, and polyphenylene sulfide is a crystalline polymer. The unstretched fiber has a large amorphous region (crystallinity is about 5%), crystallization exotherm occurs at 125℃, and glass transition temperature is 150℃. The melting point is 2865438 0℃.
