National Fluoromers proudly manufactures, supplies, and exports Graphite Filled PTFE—an advanced composite material designed for superior performance in dynamic, high-friction environments. By blending virgin PTFE with 5% to 20% graphite, we create a material that retains PTFE’s chemical and thermal resistance while significantly improving its self-lubrication, thermal conductivity, and wear resistance.

This grade is ideal for dry-running or intermittently lubricated systems, such as pumps, valve components, slide rings, and dynamic seals.

What is Graphite Filled PTFE?

Graphite Filled PTFE is a high-performance compound made by incorporating fine graphite powder into the PTFE matrix. Graphite acts as a solid lubricant, reducing surface friction and enabling the PTFE to withstand demanding motion, pressure, and temperature cycling without deformation or excessive wear.

This blend is optimal for dynamic applications requiring smooth movement, minimal heat buildup, and extended component life.
