Stadiums waterproof breathable layer of polyethylene polypropylene breathable waterproof membrane, suitable for wall, pressure plate, wood walls and sloping roof junction, this product uses a different breathable formula, production technology to produce different amounts of ventilation products, breathable amount from (300-3000g / m2 / 24h), product spread on building roof insulation, at the same time strengthening the building watertight, breathable its unique features that make the smooth discharge of moisture, so as to effectively maintain the building life, played insulation, energy-efficient, improve the function of the living environment. Class A: LB series, low permeability product, the widest width 2.2 m; Class B: HB series, high permeability, temperature 80 degrees, the widest width 1.8 m; Class C: CB series, high permeability, using the latest science and technology, to overcome the past, most manufacturers use glue compound disadvantage, using pure thermal compound technology, without glue, it is possible to temperature above 100 degrees, the surface smooth, wrinkle-foaming, good fastness, high strength and air permeability, high-strength anti-aging, which is currently the real products can meet EU standards. (Just north of the Yangtze Our company can produce such products.) Waterproof breathable membrane works: As the smallest droplet diameter of about 20 microns, and water vapor molecules is only about 0.0004 microns in diameter, there is a huge difference between the two diameters, water vapor diffusion theory can borrow through microporous breathable membrane, liquid water or water because the surface tension, the water molecules can not pass, it prevents water penetration occurs. The main benefit of breathable waterproof membrane: 1. waterproof breathable membrane while strengthening the building watertight, so that the structure of water vapor quickly discharged, protect building envelope thermal performance, avoid mildew breeding roof, improving indoor air quality. 2. waterproof breathable membrane laid on top of the insulation layer and sailing, waterproof vapor-permeable membrane between two pieces of natural drooping sails, nail holes at the highest point, the rain is not easy to fleeing, waterproof more secure. 3. breathable waterproof membrane to protect the insulation layer, on top of the insulation layer does not need to meticulous stone concrete, can reduce the cost of the roof. Currently, breathable waterproof membrane has a very wide range of markets in European countries, the construction industry in these regions is an essential product. Mainly exported to the UK, Poland, Finland, Sweden, Norway, Italy, Greece, Cyprus, Ukraine, the Netherlands, Latvia, Southeast Asia, Australia, New Zealand and other countries and regions. Our factory advantages: 1, the size of our factory has many years of production experience and history, the factory, the product quality, production technology in the industry reputation, products factory have to undergo a rigorous inspection and repeated tests, passing behind I leave the factory. 2, our products directly to users, there is no intermediate links, to provide timely and effective guarantee for a special service or custom-made products! The main features of the product: 1: Effective blocking water, salt and other corrosive liquids, the equipment safety sensitive components in outdoor storm drain. 2: contact with water, oil, liquid can be quickly restored after breathable. 3: Intensive uniform pore distribution in a waterproof and breathable at the same time, can effectively block the dust protection rating of IP67 4: balance the pressure and prevent the sealing member surrounding air and moisture into the body, to protect the integrity of the seal. 5: protect components from the weather, can withstand immersion in water and other liquids. 6: The protected parts easy to clean, unaffected by corrosive contaminants to ensure component performance and service life. Stadiums with a water vapor permeability layer Nantong Jinwei Composite Materials Co. is an American-owned enterprises. MSC Industrial Park, located in Nantong City. The company covers an area of ??20,000 square meters, with standard modern workshop and advanced processing equipment. Combined with Germany, Italy and the international advanced technology, based on the ISO9001 quality management system, professional production of non-woven, breathable waterproof membrane, composite nonwovens, SMS nonwovens, filtration materials, oil-absorbing cotton. Products: polymer waterproof breathable membrane is a composite with spunbond non-woven polypropylene and polyethylene film is made, the product has a good waterproof, breathable and anti-aging properties, the product has a unique respiratory function, you can make the water freely through the air, but condenses into water can not penetrate, thus ensuring a dry and comfortable inside the building, while avoiding damage to buildings dew condensation of water to maintain the structure (roof and walls).
