Carbon filled KEYLON® PTFE is a specialized PTFE grade developed for situations where standard PTFE is not enough. By adding carbon, the material delivers better thermal and electrical conductivity, while also improving wear performance and compression behavior in loaded parts.

PTFE + 25% Carbon

This grade is especially useful in components that face continuous movement, pressure, and heat generation. The added carbon helps the material manage friction more effectively, which can support longer service life in demanding operating conditions.

In sliding service, carbon filled KEYLON® PTFE offers strong abrasion resistance along with dependable load-bearing performance. It works well in systems ranging from dry running environments to fully lubricated applications, making it a versatile option for many industrial uses.

Our KEYLON® carbon grade provides 10% better wear life than conventional carbon grades, which makes it a practical choice when durability is a priority.

Key characteristics include:

• Higher thermal conductivity than conventional PTFE
• Improved electrical conductivity compared with standard PTFE
• Better wear life under continuous motion
• Good compression properties for loading applications
• Solid abrasion resistance in sliding contact
• Reliable performance from dry to fully lubricated systems

APPLICATIONS:

Carbon filled KEYLON® PTFE is commonly selected for dynamic parts that operate at high speed, where heat buildup can accelerate wear. Because the material conducts heat more effectively, it helps reduce the wear caused by elevated temperatures during service.

Typical examples include seal rings, piston rings, and compressor rings. Its load-carrying capability also makes it suitable for higher-load gasketing applications. In addition, carbon is recognized as one of the best fillers for water applications.

For engineers and designers looking for a balance of wear resistance, conductivity, and load support, carbon filled KEYLON® PTFE offers a dependable solution. It is a strong option when a PTFE-based material must perform under friction, pressure, and heat at the same time.
