Polytetrafluoroethylene (PTFE) is used in a variety of industrial products including gaskets, bearings and parts for valves and pumps.
Please contact our sales team to discuss specific applications, but in summary PTFE offers the following characteristics:
- Low Friction
- Good Electrical Insulation
- Wide Temperature Range (from 260º+ to -200º)
- Excellent Acid & Chemical Resistance
- Chemically or mechanically etched sheet and strip is available where bonding to other components or structures is required. Thinner gauge sheeting is also available.
PTFE Sheeting
To BS 3784. Available in thicknesses from 0.5mm to 50mm and in sheet sizes from 600mm x 600mm to 1500mm x 1500mm. Chemically or mechanically etched sheet and strip is available where bonding to other components or structures is required. Thinner gauge sheeting is also available.
Virgin, Expanded or Filled PTFE
- Virgin PTFE grades are used for Gaskets in the food & pharmaceutical industries
- Expanded PTFE grades are used for damaged flange faces and glass or plastic flanges
- Filled PTFE grades are used where specific physical or electrical properties are required.
PTFE Envelope/Rubber Insert Gaskets
Standard Rubber joints can be provided with an envelope of pure PTFE to protect the exposed joint edge from corrosive attack, or for applications where hygiene conditions are essential. In addition we stock a wide range of PTFE envelopes to suit standard pipe flanges and special envelopes can be fabricated to almost any given size or insert.
