Details

　　Performance characteristics of waterproof membrane:

　　Excellent anti-seepage; high barrier properties; high puncture resistance; no chemical pollution; acid, alkali and various chemical substances; excellent elongation and wear resistance; good dimensional stability; good adhesion; easy construction.

　　Main uses:

　　Urban garbage landfill, coal ash dam treatment, roads, railways, drainage projects, water conservancy, tunnels, dikes, dams, gates, liquid storage reservoirs, water, oil, liquid infusion channels, solid waste storage yards, roofs, building basements, underground warehouses, underground garages, moisture-proof, pile membrane cofferdams, sea reclamation, wharf projects, etc.

　　Geometric dimensions:

　　Thickness: 0.20-2.00mm; Width: 1000-5000mm (thickness 0.5mm or less can reach 16M).

　　PVC waterproofing membrane technical parameters:

　　The waterproofing membrane produced by polyvinyl chloride (PVC) material has low cost, good aging resistance and UV resistance, certain tensile strength and elongation at break, large shrinkage rate, good low-temperature flexibility, and convenient construction. There are mechanical fixing, heat sealing, cold bonding and other methods. Especially used for roof waterproofing. The physical properties of the PVC waterproofing membrane produced by our company can basically reach the advanced level of similar international products. PVC physical and mechanical standards (GB12952-2003).
