PTFE + 25 % carbon

A linear-chain polymer of great molecular length. Its structure, made of long carbon chains saturated with fluorine, gives it chemical, mechanical, electrical and thermal properties that meet the most demanding industrial requirements.

This carbon-filled PTFE has good thermal conductivity. It withstands loads with a low coefficient of friction, and its chemical and wear resistance is high.

Main characteristics

• Excellent compressive behaviour and wear resistance.
• Good thermal conductivity.
• Low permeability.
• One of the most inert fillers, except in acidic media, where glass fibre performs better.
• The carbon makes it antistatic.
• Performs well in wet conditions.

Typical uses

Seals that need high wear resistance under high pressure: piston rings for non-lubricated compressors and bearings.
