GENERAL PROPERTIES
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
