Expanded PTFE Joint Sealant

PTFE is expanded to make a soft and conformable Joint Sealant that seals faster and with less cold flow than regular PTFE. It has a peel and stick adhesive backing on one side to make installation easy. This expanded PTFE (EPTFE), can be used on flanges by overlapping at one point. Keep a roll of this and never be caught without a gasket. Ideal for use as a gasket in 99% of applications up to 600 F (depending on pressure)

Can we specify Teflon ePTFE? 

Expanded PTFE can be made from genuine Teflon™  resin.  It would then be genuine expanded Teflon™. To the best of our knowledge, the companies that produce highly fibrillated PTFE have not utilized Teflon Resin. Teflon™ can only be sold by those companies granted a trademark license from Chemours.  Major ePTFE manufacturers such as W. L. Gore do not list Teflon Resin as an ingredient, so we must assume they are not using Chemours™ resin.
