Water vapor permeability membrane is a new type of polymer vapor permeability waterproof material. Speaking from the production process, water vapor permeable membrane technical requirements than the average much higher waterproof material; and from the quality point of view, water vapor permeability film may also have other waterproof materials do not have the functional characteristics. Water vapor permeability membrane in strengthening building air tightness, water tightness while pvc waterproofing membrane, its unique vapor permeability properties of pvc waterproofing membrane manufacturers enables the rapid discharge of water vapor inside the structure for waterproofing, to avoid structural breed mold, protection of property value, and the perfect solution for moisture and on human health; vapor rapid discharge protection to maintain thermal performance, is a healthy environment-friendly new energy-saving materials. Polyethylene fiber composite waterproofing membrane waterproof layer polyethylene resin-based, two-surface composite woven polypropylene filament as reinforcing layer, hot melt process once direct pressure composite molding (low-end products are using secondary composite molding process ). Main waterproof layer polyethylene film using good puncture resistance scale linear low polyethylene (LLDPE) resin processing, while adding accessories to improve the flexibility and adhesion membrane main waterproof layer, adding carbon black, antioxidant agents to improve the aging resistance of the coil primary waterproof layer.
