PB10000 SERIES

Graphite-Filled PTFE

Graphite-filled PTFE materials have much better wear resistance than virgin PTFE materials with slightly higher coefficients of friction. Graphite-filled PTFE materials have better extrusion resistance than virgin PTFE materials.

They are typically used in seal components for rotatory and reciprocating applications and can be used to seal against steel, stainless steel, chromium plating, bronze, bare or anodized aluminum and aluminum alloys, and ceramic coatings.
