Descripción del producto

1) breathe freely film compound all kinds of non-woven (the most wide door of 1.8 meters), air-laid paper compound non-woven fabric or breathe freely film or PE membrane, this product USES microporous membrane permeability and non-woven compound and into, feel soft, breathable seepage control, the products are widely used in protective clothing, ShouShuYi and sheets for health care and protection.
2) building waterproof breathable polypropylene polyethylene polymer membrane. This product USES different breath freely formula, production technology, the production of permeability is a different product, permeability is from (*******0 g/m2/*4 h) is widely used in building waterproofing roof field.
A class (garde products) : 2.1 m, airtight or low permeability products, use A variety of different performance and raw material, A heat flow delay the compound technology, suitable for outdoor temperature is high, the drier, water vapor lower humidity region is used.
B class (high-grade products) : 1.6 meters high, breathe freely, high temperature resistant. At present domestic manufacturers are almost use hot melt adhesive spray adhesive composite technology production of high breathe freely waterproof breathable materials. Defect is breathable quantity is low, because the middle of microporous membrane permeability actually are more hot melt adhesive, in addition, the biggest drawback is very low temperature resistance, can only take the temperature of *0 degrees. Because this glue in fact similar to the stickers, hot melt adhesive itself to belong to a pressure sensitive adhesive. So, this is the production of waterproof breathable film service life is very short, only can be really waterproof breathable membrane fake and inferior products.
