PTFE Gaskets
PTFE materials, or Polytetrafluoroethylene materials, are made of synthetic fluoropolymer of tetrafluoroethylene. Most commonly known by the trademark name Teflon®, the inert nature of the material means it is highly hydrophobic, have one of the lowest coefficients of friction and is resistant to most chemicals. PTFE gaskets can be reinforced with fillers such as carbon or graphite to reduce creep under high pressures and temperatures.
We precision cut virgin and composite PTFE gasket profiles to suit a wide variety of sealing applications.
Virgin PTFE Gaskets
Has excellent chemical and electrical resistance properties with a low coefficient of friction. Often used in food, water and pharmaceutical applications.
Glass or carbon-filled PTFE Gaskets
Adding glass and carbon in the PTFE sintering process adds mechanical strength to the material and reducing creep under higher pressures.
Etched PTFE Gaskets
The non-stick characteristics of Teflon® (PTFE) mean that it requires chemical modification, or etching, in order to bond with other surfaces.
Expanded PTFE Gaskets
Virgin PTFE is expanded during manufacture, altering its structure to improve dielectric and recovery characteristics under low bolt load.
The Manufacture of PTFE Gaskets
Our PTFE Teflon Gaskets and seals are cut to precise tolerances in small or large quantities utilising in-house CNC machinery to suit customer requirements. Our manufacturing process ensures that production is cost-effective, efficient and accurate.
Our turnkey gasket manufacturing solutions have been developed to help clients with materials specification and prototyping where required. This often includes CAD gasket design, standard and bespoke manufacture and distribution. All gaskets are supplied to recognised national and international standards.
Key Features of PTFE
- Chemical resistance
- High dielectric insulating strength
- Temperatures resistance from -200°c to +260°c
- Low coefficient of friction
- Good resistance to moisture
PTFE GASKET APPLICATIONS
What is PTFE Used For?
Commonly used in pipework and flanges where chemicals are present, PTFE gaskets have an extremely low coefficient of friction and good resistance to moisture and corrosion. The anti-stick properties of the material mean PTFE is commonly found in applications with parts that have linear or rotary movements.
Often used in food and pharmaceutical processes, we supply PTFE materials that meets international hygiene standards with traceable certification available where required.
- Pneumatic Seals
- Hydraulic Cylinders
- High Speed Applications
- Aerospace
- Oil and Gas
