100% pure P.T.F.E. Hydrophobic,Windproof Pore size(micron):0.2~5 Porosity(%):80~95 Thickness(micron)10-80

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-porousmembrane offers the best combination of highly efficient filtration and separationfunctional properties.The micro-porous membrane possesses excellent chemical resistance, wide operatingtemperature ranging from -400°F to +500°F (-200°C to +260°C), excellentair 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-termstorage 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 propertyApplications: 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
