"Polyethylene polypropylene polymer waterproofing membrane" of new building materials"
2015-07-27
Polyethylene polypropylene polymer waterproofing membrane using polymer cement paste, can be in rainy days (moisture content of more than 50%) construction. Polyethylene polypropylene composite waterproofing membrane is not limited by the moisture content of the base layer below 9%, to ensure the construction progress. Polyethylene polypropylene polymer waterproofing membrane structure features: 1, three-layer structure, surface enhancement. 2, the core layer-the main waterproof layer uses a higher than the degree (macromolecular side chain) of linear low density polyethylene (LLDPE), its extensibility, water impermeability, flexibility, puncture resistance, low temperature resistance. 3. The surface is polypropylene (polyester) non-woven fabric, through the core
