Glass Filled PTFE

25% Glass Filled PTFE

The addition of glass to PTFE vastly improves the compressive strength and creep resistance and also increases the mechanical strengths of the material.
Applications for use include shaft seals, bushes, slide bearings, piston rings and thrust washers.


  • Higher hardness
  • Higher compressive strength
  • Improved wear and abrasion resistance
  • Improved thermal stability
  • Increased dimensional stability
  • Lower electrical properties than virgin grade
