Key Features

Key Features of Graphite-Filled PTFE

Graphite is a natural solid lubricant. Dispersing it into the PTFE matrix delivers four tangible improvements over unfilled PTFE — targeted at dynamic friction, wear, heat transfer and long-term loading.

  • 🔁
    Lower Coefficient of Friction
    Graphite reduces PTFE's friction — improved performance in sliding applications.
  • 🛡️
    Improved Wear Resistance
    Graphite increases wear resistance — longer service life in high-wear environments.
  • 🔥
    Enhanced Thermal Conductivity
    Graphite raises PTFE's thermal conductivity — better heat dissipation in dynamic parts.
  • 📐
    Dimensional Stability
    Improves PTFE's creep resistance — stable dimensions under long-term loading.
