PTFE Carbon Filled has good chemical resistance to corrosive environments, has better creep and wear resistance compared to standard PTFE materials.
Black carbon filled ptfe tube
PTFE Carbon Filled has good chemical resistance to corrosive environments, has better creep and wear resistance compared to standard PTFE materials. These properties are improved with the addition of a carbon filler. This filler improves dimensional stability, raises the heat deflection temperature, improves creep resistance and the dynamic bearing performance. PTFE Carbon-Filled exhibits good initial wear and rubbing/sliding contact characteristics in both dry and wet/water applications. (Temperature: -260°C to +250°C). It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.
