Polytetrafluoroethylene O-Rings
Polytetrafluoroethylene (PTFE) is a non-flammable synthetic resin produced by the polymerisation of tetrafluoroethylene and is widely used across all industries.
Hardness Range: 70 – 85 shore A
Operating Temperature: -30°C to +200°C
Typical Use:
PTFE is more often the choice for gaskets, washers and seals due to its corrosion resistance and chemically inert properties. PTFE is a staple material across all industries including aerospace and defence.
Advantages:
Excellent chemical resistance
Excellent ozone and sunlight resistance
Cost effective
Disadvantages:
Higher sealing force required in comparison to standard elastomer seals
