(OP)
I have an application where an edge trim in expanded PTFE (if such an edge trim exists) would be desirable. Is any edge trim manufactured in expanded PTFE of a shape similar to commonly available bulb-type extruded elastomer sections? I really do not know the technological limitations of making seals in expanded PTFE, but something like this would be a desirable addition to the repertoire of available extruded shapes. My application is high temperature (575 degrees F +), stationary, aggressive chemicals like bleach, detergents, tartaric acid, salt etc. while providing an atmospheric pressure water tight seal. Thanks in advance.

Be aware that unlike elastomers, ePTFE is a rather "dead" material in that it takes a set and does not rebound. This is not a problem in a bolted, flanged connection however if you're not maintaining a load on the ePTFE it will not provide a very good seal.

Thanks again.
