PTFE Products

Virgin PTFE provides an exceptional sealing material and is available in many forms, from sheet, rods, tube, machined components, in solid and expanded forms.

 

PTFE exhibits the following properties.

  1. A resistance to virtually all corrosive chemicals with the exception of fluorine, some fluorochemicals and molten alkali metals.
  2. A very low coefficient of friction.
  3. Non-flammable.
  4. Non-ageing properties.
  5. Non-toxic.
  6. Anti-stick properties.
  7. Excellent tensile strength.
  8. Moisture and U.V. resistance.
  9. Excellent dielectric properties.

 

Filled PTFE : In spite of the above properties, pure PTFE is inadequate for some engineering uses. Mechanical applications especially require better physical characteristics. A proper combination of inorganic and metallic fillers will further enhance the materials creep and wear resistance, thermal conductivity, dimensional stability and hardness. The more common fillers are 

  • 15% glass
  • 25% glass 
  • 60% bronze
  • 15% graphite
  • 15% glass / 5% graphite
  • 25% carbon.

 

PTFE is suitable for temperatures between -200°C to +260°C
