Expanded PTFE Products

Expanded PTFE tape


Expanded PTFE is a sealing agent that is made of 100-percent pure PTFE. The expansion process produces a microporous fibrous structure which gives the product its unique mechanical properties.

Expanded PTFE is a soft, compressible gasket material. It is a form-in-place gasket that conforms to almost any sealing surface. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.
