PTFE porous membrane is made of 100% expanded PTFE under special processing that creates millions of micro pores, 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, wide operating temperature ranging from -400°F~+500°F(-200°C~+260°C), 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.

Monolayer PTFE porous membrane is good as filtrate material, and applied in phamaceutical, beer fermenting, biological products. Double laminated PTFE porous membrane is good for dust resistance and meeting the demand of any other industries, such as electronic, instruments,dust-free room where air filtration is required.
