General Properties

PolyPhenylene Sulfide (PPS) offers the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and are inert to steam, strong bases, fuels and acids.

Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components.


40% Glass Reinforced PPS

This product is the most recognized filled grade of PPS. It offers better dimensional stability and thermal performance than unfilled Techtron® PPS and maintains its strength to above 425°F (220°C).

Bearing Grade PPS

Bearing grade PPS is internally lubricated and carbon fiber reinforced offering a low coefficient of thermal expansion and uncompromised chemical resistance. It is well suited for thrust or wear applications or when an electrically conductive material is required.
