Filled Expanded PTFE Gasket Glass fibre Heat Resistance For Seal

Quick Detail:
ERM sealing company is specilized in virgin PTFE gasket and filled PTFE gakset .
One of the most chemically-resistant materials available, PTFE and expanded ePTFE can fit the bill for extreme sealing with sheet gasketing, gasket tape, joint sealant, and universal gasket configurations.
In order to improve the ptfe capability . We filled  Glass fibre , carbon fibre. Copper,  Moly , graphite , peek and other material .
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
