Material Properties

While virgin PTFE offers the lowest friction of any solid, it has poor wear resistance and creeps under load. Filled PTFE compounds address these limitations with fillers that dramatically improve mechanical properties.

Glass fiber for general improvement, carbon/graphite for wear and thermal conductivity, bronze for thermal and electrical conductivity.

  • 100x better wear resistance vs virgin PTFE
  • Reduced creep and cold flow
  • Enhanced compressive strength
  • Maintains chemical resistance
  • Tailored for specific applications
Common Filler Types
Glass (15-25%)General purpose, wear & strength
Carbon (25%)Best wear, thermal conductivity
Graphite (15%)Self-lubricating, FDA compliant
Bronze (40-60%)Thermal & electrical conductivity
MoS2 (5%)Enhanced lubricity
Carbon + GraphiteMaximum wear resistance
