GENERAL PROPERTIES
click to resize photo Tecatron ® 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 GRADES
Tecatron ® (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

NOTE:
Many other filled grades of PPS are also available in stock shape forms.
