Description:

Our most common PTFE filled grades include:


PTFE, Glass Filled Gaskets

  • Added in various amounts (5% to 40%)
  • Increases compressive strength
  • Rigidity and wear
  • Reduces creep and cold flow
  • Minimal effect on chemical and electrical properties
  • Used in applications to decrease cold flow

PTFE, Carbon Filled Gaskets

  • Added in various amounts (10% to 35%)
  • Increases compressive strength
  • Hardness, wear and load properties
  • Good chemical resistance
  • Various types and amounts of carbon can be added to alter conductivity

PTFE, Graphite Filled Gaskets

  • Added in various amounts (5% to 15%)
  • Reduces coefficient of friction
  • Reduces initial wear
  • Increases strength
  • Compatible with most hydraulic fluids
  • Outstanding performance in hydraulic/pneumatic compression type rod and piston seals, bearing bands and rotary applications
