PPS — semi-crystalline high-performance polymer. 220 C service temperature, exceptional chemical resistance. For automotive fuel system components, chemical pump parts and electrical connectors.
PPS (Polyphenylene Sulphide) per ISO 10112 is a semi-crystalline thermoplastic with the best chemical resistance of any melt-processable engineering plastic combined with excellent flame retardance (V-0) and dimensional stability. Continuous service temperature 180-220 C. Used for automotive fuel system components, chemical pump parts, electrical connectors and PCB-mount components.
