Polyphenylene sulfide (PPS), full name of polyphenylene sulfide, English name of Polyphenylene sulfide, referred to as PPS (hereinafter referred to as PPS or PPS). The molecular structure of polyphenylene sulfide is relatively simple. The main chain of the molecule is alternately arranged by benzene ring and sulfur atom. A large number of benzene rings endow polyphenylene sulfide with rigidity, while a large number of sulfide bonds provide flexibility. Symmetric molecular structure, easy to crystallize, non-polar, good electrical performance, non absorbent.

The outstanding properties of PPS include: good heat resistance, which can be used in the temperature range of 200-240 ℃; The corrosion resistance is close to that of polytetrafluoroethylene; Excellent electrical performance; Excellent mechanical performance; Good flame retardancy; The dimensional stability of the products is good, which can be processed by a variety of processing and molding methods, and can be precisely formed.

Pure PPS is rarely used alone because of its brittleness, and most of the PPS used are its modified varieties. Specific: glass fiber reinforced PPS, glass mineral fiber reinforced PPS, carbon fiber reinforced PPS, etc.
