Medical pu film has good elasticity and is slightly high. In terms of waterproof property, although the thickness is extremely thin (0.012-0.035mm), it has physical properties that other materials cannot match (the water pressure can be withstood above 10000mm water column). Using high-tech technology to introduce hydrophilic agent into the material, the film has better moisture permeability (human sweat can freely penetrate between films) in addition to high waterproof property. The breakthrough in this function, together with the fitting processing technology of the textile industry, greatly improves the added value of textiles. Now it is widely used in snow clothing, windbreaker, cold jacket, gloves.
PU is polyurethane, and PU skin is the skin of polyurethane components. Now clothing manufacturers widely use this material to produce clothing, commonly known as imitation leather clothing PU is the abbreviation of "ploy urethane" in English. The Chinese chemical name of polyurethane also has good or bad quality. Most good bags use imported PU skins; PU leather is generally the second layer of leather with cow leather on the reverse side, and the surface is coated with a layer of PU resin, so it is also called film cow leather. Its price is cheap and its utilization rate is high. With the change of technology, it is also made into various grades of varieties, such as imported two-layer cow leather. Because of unique technology, stable quality, novel varieties and other characteristics, it is a good leather at present, and its price and grade are no less than the first layer leather. PU leather and real leather bags have their own characteristics. PU leather bags are beautiful in appearance, easy to take care of, low in price, but not wear-resistant and easy to break; Real leather is expensive, troublesome to take care of, but durable.
PU value is a pasteurization unit. The sterilization effect caused by one minute at 60 ℃ is a pasteurization unit, that is, a PU value. The calculation formula is: PU=Z · 1.393 (t-60). Where Z is time and t is temperature. It is widely used in the packaging workshop of beer and beverage industry, and is usually used as an important indicator to assess the quality of finished products.
