Pore-forming Characteristics of Polytetrafluoroethylene Plastic Resin,microporous film made by bidirectional stretching method. The surface of the membrane can reach more than one billion micropores per square centimeter.,the diameter of each micropore(0.1 ym-0.5m)specific water molecule diameter(20μm-100pm)hundreds of times smaller,ratio of water vapor molecules(0.0003m-0.0004m)tens of thousands of times larger,enables water vapor to pass through,and water droplets cannot pass through,use of this microporous structure can achieve excellent waterproof and moisture permeability function;In addition, because the hole is extremely small and the longitudinal irregular bending arrangement,makes the wind unable to pass through.,thus has the characteristics of wind resistance and warmth retention. After compounding with other fabrics,is widely used in military clothing,medical clothing,casual clothing,special protective clothing for fire fighting, anti-virus and flooding operations,outdoor sportswear,shoes, hats, gloves and other down products, home textile accessories and sleeping bags, tents, rain gear and other materials.

characteristics:

1. has excellent waterproof performance and can effectively block rainwater.
2. has good air permeability, sweat is effectively eliminated, and human comfort is maintained.
3. has good abrasion resistance and washing resistance.
