When used as a non-metallic bearing, Tecapeek™ PVX offers a superb range of tribological performance. It is designed to run at high loads and speeds, in hostile environments, either dry or lubricated.
- High temperature performance.
Continuous use temperature over 450° F.
- Flammability is 94VO with a low limiting 02 index (= 40%) and very low smoke generation.
- Can be used dry against hard or softmatting surfaces.
- Excellent weather resistance.
|
- Resistant to gamma radiation.
- Complies with specific provisions of ASTM D6262-98.
- Available in a wide range of extruded sizes of rod and plate for subsequent machined parts.
