PB10000 SERIES

Carbon Fiber-Filled PTFE

Carbon fiber raises hardness, lowers creep, and increases compressive and flexural modulus. The advantage of using Carbon fiber instead of glass fiber is that Carbon fiber is inert to HF and strong bases.

Carbon fiber-filled PTFE materials have higher thermal conductivity and a lower coefficient of friction than their glass fiber counterparts. Carbon fiber-filled PTFE materials have a long wear life and excellent extrusion resistance. As their glass fiber equivalents, carbon fiber-filled PTFE materials are used in seal components for static and dynamic application and against chromium plate and steel.
