EXPANDED PTFE (ePTFE) GASKET SEALING TAPE
Expanded PTFE sealing tape is a cord or tape of pure PTFE extruded by a special process that expands and orientates the PTFE, making it soft and flexible. It is for use in flanged joints which are permanently bolted.
Adtex ePTFE tape is supplied as a cord or thick tape form with a self-adhesive strip to allow easy installation on vertical surfaces.
Being microporous, ePTFE is significantly different to conventional PTFE tubing – the material is air-permeable, soft & flexible, and feels somewhat like smooth, spongey marshmallow to the touch.
It is also chemically resistant with high linear strength, chemically inert, remains watertight at low pressure, has a low dielectric constant, and offers excellent radial expansion and UV resistance too.
Expanded PTFE joint sealant tape is available from stock in different widths, from 3mm to 20mm, and various thicknesses, from 1.50mm to 7mm. Find our Expanded PTFE Sealing Tape Sizes.

These unique properties are used to advantage in Adtex ePTFE gasket sealing tape, where one product can be used to seal virtually all flange faces in process plants, in process conditions of up to 260°C.
ePTFE tape can therefore be used as a universal joint sealant, eliminating the need to stock different grades of gasket for different chemicals and process conditions.
As it is supplied in tape form, different gasket sizes no longer must be stocked.
