[0002] Polyurethane film has good elasticity and high strength. Although it is extremely thin (0.012-0.035mm) in waterproofness, it has physical properties that other materials cannot match (it can withstand water pressure above 10,000mm water column). By using high-tech technology to introduce hydrophilic agents into the material, the film not only has high waterproof performance, but also has excellent moisture permeability (human sweat can freely penetrate through the film). This functional breakthrough, combined with the textile industry's lamination processing technology, has greatly increased the added value of textiles. It is now widely used in snow suits, windbreakers, cold-proof jackets, gloves, hats and bedspreads.
