        Welcome to Beifang Waterproof. Ancient have positive Dayu, this is Beifang Waterproof !

        Polyvinyl chloride plastic sheets for waterproofing

        Product introduction:

        HGP-200 series PVC waterproof material is made of PVC resin as the main body, adding anti UV agent, anti-aging agent, antioxidant and other chemical additives, after heat mixing, extrusion, calendering, cooling and other processes made high performance elastic waterproof material.

        • Advantages
        • Specification
        • Performance

        1, aging resistance, long service life. Roofing materials up to more than 20 years and underground for 50 years;

        2, the tensile strength, elongation, heat treatment size change is small;

        3, low temperature flexibility, adapt to the environment temperature difference;

        4, chemical corrosion resistance, good plasticity, edge detail processing;

        5, convenient construction, reliable, easy maintenance, low cost, no pollution.
