Modified PTFE

Our Modified PTFE (also know as a second generation) has a lower deformation under load, good welding characteristics with the same, excellent chemical resistance and thermal stability. Its molecular weight is one fifth PTFE, allowing the particles to fuse better, therefore the modified PTFE has a lower permeability and better compression stress relaxation, especially at higher temperatures. It has more elasticity perfect for PTFE welded tapes, PTFE envelopes, cryogenic applications, valve seats and also back-up rings.
