click to resize photo Techtron® 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.

Techtron ® (unfilled)
As an unfilled material, Techtron® is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a lower-temperature replacement for PEEK. Standard Techtron® PPS is off-white in color.

Techtron ® PSGF (40% glass filled)
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).

Unfilled Techtron® PPS is FDA and USDA compliant.

• High pressure liquid chromatography components • Wafer retaining rings for CMP polishing • Hydrocarbon pump, valve, and compressor components • Oil field parts • Aerospace components • Medical and diagnostic device parts
