1. Introduction of the product
The product is made up of 3 portions: polyester/ glass fabric mat as reinforcement providing strong supporting; APP as modifier providing better performance; polyethylene film / aluminum film / sand grain / colored sand at el. materials as surface coat.
2. Implement national standards: 18243-2000
APP modified bituminous Waterproofing membranes belong to the class of plastic body modification. The structure of APP molecule stabilizes to exist a long time, accordingly, the product performance a good capability, which can be used for high temperature place mostly.
