PPS (polyphenylene sulfide)
PPS GF-40 (polyphenylene sulfide glass-fiber reinforced)
Polyphenylene sulfide has inherent flame resistance, suprior electrical properties, and is non-hygroscopic. Dute to its heat deflection temperature, PPS GF-40 retains its mechanical properties up to 425°F. PPS GF-40 is a glass-fiber-reinforced semi-crystalline engineering thermoplastic capable of withstanding virtually all chemical contact up to 400°F. It is an excellent choice for corrosive, high-temperature applications which require the mechanical properties of a glass-reinforced thermoplastic.
