Product Description
Product Details
3 layer breathable roof membrane, thermal laminated by high polymer material + polyolef in microporous membrane + high polymer material, we create this technology in China which is advanced all over the world.
Product Details
Polyolefin microporous membrane has excellent breathability, as well as good duration. Polyolefin microporous membrane has not only acid and alkali resistance, but also good extensibility which enable the fasresilience after tearing by nail so that to improve the sealing performance.
Product Details
Breawarf breathable roof membrane adopt the principle of microspore. The minimum diameter of water drop is about 20 micron while the diameter of water vapour molecule is about 0.0004 micron, because of the enormous difference, water vapour can get across according to the dif fusibility, while water molecule can't pass because of the surface tension
Specification
Waterproof breathable membrane has excellent performance at water resistance, meanwhile with particular function of high vapor permeability, which mainly use used in construction as underlay on pitched roofs or walls.
It has three layers by Hot pressing composite technology:on the top and bottom is:polypropylene Spunbond non-woven fabric,between the two layers, is polyethylene material to form breathable film.
