Detailed Product Description

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 -400°F to +500°F (-200°C to +260°C), 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: -400°F ~ +500°F (-200°C ~ +260°C)

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
