Polyphenylene sulfide (PPS) offers the best chemical resistance with no known solvents below 392°F (200°C). it's low moisture absorption, good mechanical and excellent thermal resistance properties make PPS ideally suited for precise tolerance machined components.
Polyphenylene sulfide (PPS) is a semi-crystalline engineering thermoplastic. It is suitable for applications requiring thermal stability to 425° and structural integrity to 225°. A very low coefficient of linear thermal expansion, combined with stress-relieved manufacturing, make unfilled PPS ideally suited for precise-tolerance machined components. PPS is well suited for structural applications in corrosive environments or as a lower-temperature replacement for PEEK. Its low ionic impurities make it an excellent choice for applications where high purity is a concern.
Additional PPS grades are available, i.e., glass filled, glass/mineral filled, internally lubricated, and formulations within these grades which offer low friction, high limiting PVs, bearing strength, wear resistance, heat stability, increased impact strength and static control properties are available to meet various requirement levels. Contact an Emco Industrial Plastics representative who can help you choose the correct material to meet specific application demands.
