PolyPhenylene Sulfide (PPS) material series is a semi-crystalline engineering thermoplastic that offers the broadest resistance to chemicals of any high-performance melt fluoropolymer resin. There are no current solvents that affect PPS under 392º F, and it is inert to steam, strong bases, fuels, and acids.

PPS is ideal for precise tolerance machined components because it has minimal water absorption, has a very low coefficient of linear thermal expansion, and is stress-relieving manufactured.

PB40000 materials are also a great option for structural applications, harsh corrosive environments, and a lower temperature replacement for PEEK. At moderate temperatures, PPS offers great dimensional stability and strength as compared to most other comparable resin choices.

PB40300R - 40 Glass Fiber PPS

PB40300 is our compression molded PPS reinforced with 40% glass fiber. It offers impressive dimensional stability and an exceptional degree of thermal stability, all while maintaining its strength above 425° F.

With its superior chemical and flame resistance and excellent mechanical and electrical properties, PB40300 provides superior performance over a wide range of critical design requirements.

Excellent processing characteristics allow PB40300 to meet the needs of demanding, high-precision applications without hesitation!
