PTFE porous membrane is made of 100% expanded P. T. F. E. Under special processing that creates millions of micro-pores, nodes and connected fiber. This micro-porous membrane offers the best combination of highly efficient filtration and separation functional properties.

The micro-porous membrane possesses excellent chemical resistance, wide operating temperature ranging from -400F to +500F (-200C to +260C), excellent
Air permeability, vapor transmission, water-proofing, and thermal isolation properties. This micro-porous membrane is the ideal material for a wide range of applications that other material cannot rival.

Features:
1) 100% pure P. T. F. E.
2) Unaffected by common chemicals, pH value range 0-14
3) Wide operating temperature: -400F ~ +500F (-200C ~ +260C)

4) Aging deterioration resistance: No deterioration and contamination after long-term storage
5) Resistance cold flow and creep relaxation: Excellent cold flow and creep resistance, overcome disadvantages of traditional PTFE products
6) Low friction
7) High porosity with superior air permeability property

Applications:
1) Air, vapor permeation and waterproof performance
2) Filter and separation performance
3) Low dielectric constant and insulated performance
4) Heatproof, temperature and chemical resistance material
5) Biotech, sensor, and optical materials
