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.

The structural characteristics of polyethylene polypropylene polymer waterproofing membrane:

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, which solves the problem of large linear expansion coefficient of polyethylene by compounding with the core layer. The roughness of the surface of the product is increased, the friction coefficient of the product is improved, and the bonding problem of the composite coil is solved, and the cement bonding is realized.
