PPS

Polyphenylene sulfide (PPS) is a high-performance engineering thermoplastic featuring an aromatic backbone with sulfide linkages, conferring exceptional thermal stability and chemical resistance. It is widely employed in aerospace, automotive, and chemical processing industries where sustained exposure to elevated temperatures, aggressive chemicals, and mechanical stress demands material durability—notably in fuel system components, electrical connectors, pump housings, and composite matrix resins. Engineers select PPS over commodity polymers when dimensional stability at temperature, flame resistance, and compatibility with harsh operating environments are critical, and over thermosets when reprocessability and injection-moldability are advantageous.
