Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene (PTFE)

Teflon (polytetrafluoroethylene) is a material with an extremely low coefficient of friction. It is resistant to almost all known elements, chemicals, and solvents. The following varieties of PTFE products are available: 

PTFE with glass fibres (approx. 25%)

PTFE with bronze (approx. 40%)

PTFE with graphite (approx. 15%)

PTFE with carbon and graphite.

TEFLON PROPERTIES:

  • High heat resistance.
  • High resistance to chemicals and solvents.
  • Non-stick properties.
  • Good dielectric properties.
  • Low coefficient of friction.
  • Physiological inertness.
  • Low mechanical resistance, hardness and stiffness.
