PTFE Gasket Material

General Properties of PTFE

PTFE (polytetrafluoroethylene) is totally unique. It is an inert material, therefore it has excellent resistance to most mineral and organic chemicals such as acids, bases and solvents. It can be used in temperatures up to approximately 260ºC.

PTFE is generally used in the presence of aggressive chemicals as it is inert. It can be supplied as a bore liner to shield pipe gaskets from chemical attack: these are supplied to fit specific bore sizes and are known as PTFE envelopes.

PTFE has the same co-efficient of friction as ice on ice, so it is an exceptionally non-stick material. More information about PTFE can be found in the following guide to PTFE.
