PTFE Sheet - Carbon Filled

PTFE Sheet - Carbon Filled

Carbon filled PTFE sheet provides improved dimensional stability and lower coefficient of thermal expansion in comparison to standard grades of PTFE. It is highly resistant to chemicals, offers good compression strength and is classified as partially electrically conductive and anti-static. 25% carbon filled PTFE offers enhanced resistance to creep, deformation and wear in comparison to the Virgin alternative, but the materials mechanical strength is still fairly limited when compared to other engineering plastics such as polyethylene. In comparison to glass filled PTFE, the material provides lower deformation under load and offers enhanced kinetic coefficient of friction.

The polymer is commonly used in high speed applications when dissipation of electric charge and low co-efficient of friction is required. Carbon filled PTFE sheet is commonly machined into shaft bearings, gaskets, shaft seals, pump components and parts used in electronic applications. At PAR Group, we have the capability to machine PTFE into bespoke requirements from drawings or existing samples utilising in-house CNC machinery.

Key Features

  • Temperature: -200°C up to +260°C.
  • Chemically inert (with the exception of elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperatures and pressures).
  • Partially electrically conductive and anti-static (volume / surface resistivity of 10³ Ohms).
  • Improved dimensional stability and creep resistance over standard grades of PTFE.
  • Improved dynamic bearing performance.
  • Good sliding properties.

Please note: Minimum order quantities and long lead times may apply.

Due to the nature of PTFE and the manufacturing process, sheets less than 6mm thick may not be flat in appearance. Thicker sheets are generally moulded which can help to ensure a flat appearance. Tolerance on thickness for PTFE is ± 5% overall, or ± 1mm or ±2mm (whichever is the greater). Other sheet sizes and thicknesses may also be available, please enquire.
