PTFE Porous Membrane For Fuel Cell

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: 

As key components of the PEMFC Special attention is paid to research of proton exchange membranes PTFE porous membrane(polytetrafluoroethylene) has been used as substrate in preparation of reinforced proton exchange membranes due to its excellent chemical and dimensional stability to satisfy requirement of PEMFC Development trend of this kind of membranes is prospected
