PTFE fiber has a tensile strength nearly 16 times that of pure PTFE sheet material and therefore TeXLon™ can sustain far greater working loads without cold flow.

Glass filling increases PTFE’s very low co-efficient of friction but considerably increases Wear and pressure resistance

The PTFE sheet may include microporous PTFE as well as expanded microporous PTFE.

The ePTFE membrane is preferably made from a blend of a PTFE homopolymer and a modified PTFE polymer.

The skin may be unalloyed nylon or acetal, or may include PTFE and/or silicone and/or molybdenum disulphide.

Each of the PTFE films is reinforced with a PTFE woven fabric.

The fluorinated thermoplastic material is a PTFE or PTFE with additives; MoS2, tungsten sulphide, titanium sulphide or titanium iodide may be used as metal compounds.

The materials used, PTFE, EPDM, PEEK and high-purity stainless steel 1.4435, were selected according to strict hygienic criteria.

  The PTFE resin comprises PTFE having a two-dimensional branched structure in the molecule.

There is provided a sterilisable vent, for use in a sterilisation apparatus, formed of a porous composite material, the composite material comprising expanded PTFE membrane and a layer of non-expanded sintered porous PTFE attached to the expanded PTFE.

The materials used, PTFE, EPDM, PEEK and high-purity stainless steel 1.4435 (316L), were selected according to strict sanitary criteria.

the inner diameter of the PTFE tube

Provided is a polytetrafluoroethylene (PTFE) porous membrane.

The present invention relates to a polytetrafluoroethylene (PTFE) tube, and more particularly to a PTFE tube for a flexible hose.

The fluororesin is any of PFA, PTFE, and a PFA/PTFE mixture.
