Product Description
House Dress Jinbo ®waterproof breathable membrane is a new type of waterproof breathable material made from spunbond polypropylene composite polymer. In terms of production process, its technical requirements are stricter than ordinary waterproof material's. Meanwhile, in terms of quality, it has unique functions that other waterproof material does not have. Its working principle is micro porous vapor permeation. The smallest diameter of the droplet is about 20 microns, but the water vapor molecule is only about 0.0004 microns in diameter. So there is a huge difference in the diameter of them. The water vapor can be discharged through the micro holes on the basis of diffusion principle. Liquid water or water drop have surface tension so that water molecules can not be discharged. Therefore, House Dress Jinbo ®waterproof breathable membrane can proof water and permeate vapor.
