Product Name:Polyphenylene Sulfide (PPS)
English Name:Polyphenylene Sulfide (PPS)
CAS No.:25212-74-4
Aliases:Polyphenylene sulfide, Poly(p-phenylene sulfide), PPS
Molecular Formula:(C6H4S)n
Physical Properties:PPS (Polyphenylene Sulfide) is a linear crystalline high-performance thermoplastic engineering plastic. Its structural unit molecular weight is about 108.16, density about 1.35 g/cm³, melting point approximately 280–300°C, thermal decomposition temperature above 400°C, and long-term service temperature 220–240°C. It exhibits excellent flame retardancy (UL 94 V-0), chemical resistance, dimensional stability, and electrical insulation, with low water absorption and insolubility in most organic solvents.
Uses:It is widely used in electronics, electrical appliances, automotive, machinery, chemical engineering, and precision instruments. Typical applications include connectors, relays, coil bobbins, automotive engine compartment components, pump housings, valves, high-temperature insulation parts, and precision structural parts.
Technical Specifications:
Flame retardancy: UL 94 V-0 (some grades V-1/V-2)
Glass fiber/mineral filled reinforcement with filler content of 20%–65% for improved strength, rigidity, and dimensional stability
Excellent long-term heat resistance with continuous service temperature of about 220–240°C
Excellent resistance to acids, alkalis, and organic solvents
Good electrical insulation; some grades offer conductive, antistatic, or low-friction (PTFE/carbon fiber) modifications
