TPO waterproofing membrane, is thermoplastic polyolefin waterproofing membrane, it is based on thermoplastic polyolefin (TPO) synthetic resin which combines ethylene propylene rubber and polypropylene with advanced polymerization technology, adding antioxidant and anti-aging agent. The new waterproof membrane made of softener can be made of polyester fiber mesh cloth as internal reinforcement material to make reinforced waterproof membrane. It is a synthetic polymer waterproof membrane waterproof product.
In practical application, the product has the comprehensive characteristics of anti-aging, high tensile strength, large elongation, wet roof construction, no need for protective layer, convenient construction and no pollution. It is very suitable for light energy-saving roofing and large-scale factory building. And waterproof layer of environmentally friendly building.
