GENERAL PROPERTIESTechtron® 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.
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
