Description

PPS is a semicrystalline thermoplastic, reinforced with glass fiber or mineral fillers. It shows excellent mechanical properties, high thermal stability, excellent chemical resistance, excellent flame retardance, good electrical and electronic properties, and good mold precision. Recently developed linear type PPS additionally shows improved properties of elongation and toughness and opens the new route for the use of a neat polymer.

Application areas

Poly( p-phenylene sulfide) (PPS) is mainly used in the reinforced form with glass fiber or mineral fillers as a high-performance thermoplastic. It is used for electrical and electronic parts (e.g., plugs and multipoint connectors, bobbins, relays, switches, encapsulation of electronic component, etc.), automobile parts (air intake systems, pumps, valves, gaskets, components for exhaust gas recirculation systems, etc.), and as components for mechanical and precision engineering. Nonfiller PPS is used for fiber, film, sheet, nonwoven fabric, etc.
