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.
Frequently Asked Questions
1. What are PTFE gaskets?
PTFE gaskets (polytetrafluoroethylene gaskets) are high-performance sealing components used to prevent leaks between flanges and pipe connections. Known for their durability and reliability, PTFE gaskets are widely used across UK industries requiring chemical resistant gaskets and long-lasting sealing solutions.
2. What are PTFE gaskets used for?
PTFE gaskets are used in applications where chemical resistance, hygiene, and temperature stability are critical. Common uses include:
Chemical processing and handling
Food and beverage manufacturing
Pharmaceutical production
Oil and gas systems
Water treatment facilities
These industries rely on PTFE flange gaskets for safe, contamination-free sealing.
3. What are the advantages of PTFE gaskets?
PTFE gaskets offer several key benefits:
Outstanding chemical resistance to acids, alkalis, and solvents
Wide temperature range (-200°C to +260°C)
Non-stick, low-friction surface for easy installation
Suitable for food-grade and hygienic environments
Long service life with minimal maintenance
This makes them a preferred choice for industrial PTFE gasket applications in the UK.
4. Are PTFE gaskets suitable for high temperatures and pressures?
Yes, PTFE gaskets perform reliably in high and low temperature environments, maintaining their sealing integrity across extreme conditions. For higher pressure applications, filled or reinforced PTFE gasket materials can be specified to improve strength and performance.
5. Can PTFE gaskets be custom made?
Yes, custom PTFE gaskets can be manufactured to suit specific flange sizes, thicknesses, and application requirements. Customisation ensures optimal sealing performance for both standard and specialist industrial systems.
