PTFE porous membrane is made of 100% expanded P. T. F. E. Under special processing that creates millions of micropores, nodes and connected fiber. This microporous membrane offers the best combination of highly efficient filtration and separation functional properties. The microporous membrane possesses excellent chemical resistance, excellent air permeability, vapor transmission, water-proofing, and thermal isolation properties. This microporous membrane is the ideal material for a wide range of applications that other material cannot rival.
