What is expanded ptfe sheet?

Expanded ptfe sheet (eptfe sheet) is made of 100% polytetrafluoroethylene through many special processes,Its internal structure is criss-cross fibers,Having the same tensile,These microfibers form numerous pores, allowing the expanded PTFE to bend arbitrarily,So it has very strong creep resistance,Also easy to cut, very suitable for the need for flange sealing needs,Expanded polytetrafluoroethylene (ePTFE) has excellent chemical resistance, abrasion resistance and extremely high and low temperature resistance, which is very suitable for the transport and sealing of industrial liquids.
