Techtron ® PPS (PolyPhenylene Sulfide) SpecificationS

GENERAL PROPERTIES
Techtron Material (c)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.

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 ® is off-white in color, but is also available in a compression-molded version which is black in color.

Unfilled Techtron ® PPS is FDA and USDA compliant.

APPLICATIONS
• 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
