PTFE micro-porous film

PTFE micro-porous film is produced by special dual-elongation processing to get the light-weight and pliable film. Which thickness is 0.025mm, opening rate is 82%, maximum diameter of the pore is 0.2 ,There are about 9 billion pores per square inch the diameter of pores are 20 times the bigger than the molecular of water, 20 thousands the smaller than the water drop. Which gives the film excellent wind-proof, water-resistant, warmth-keeping, breathable and stable performances. So the film is the right material to make high-class laminated fabrics, Meanwhile, it is also widely used in the construction and water treatment fields for it has the excellent water-resistant ability and special micro-porous structure. The film meets the requirement of the standard of "Q/HS004-2000 PTFE Film Standard”
