GENERAL PROPERTIESTecatron ® PPS (formerly known as Ensifide ®) 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.
TECATRON (ENSIFIDE) PPS GRADESTecatron ® (unfilled)
As an unfilled PPS material, Tecatron® is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a lower-temperature replacement for PEEK. Tecatron® is off-white in color.
Tecatron ® GF 40 (40% Glass Reinforced)
This product is the most recognized filled grade of PPS. It offers better dimensional stability and thermal performance than unfilled Tecatron ® PPS and maintains its strength to above 425°F (220°C).
Tecatron ® PVX (Bearing Grade)
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.
APPLICATIONS Wafer clamping rings for semiconductor processing light sockets sensor housings catalyst supports flanges thermal/electrical insulators pump housings chip carriers valve bodies switch and plug parts
Many other filled grades of PPS are also available in stock shape forms.
