Waterproofing Membrane RSA-821 polymer modified waterproofing membrane CE Certificated China well known trade mark"Yuhong"Brand It is the curly waterproofing material that uses filament polyester non-woven fabric as embryo substrate and adopts specially-prepared polymer modified asphalt as the dipcoating material. As to the isolating material, its lower surface is covered with PE film (white) and the upper surface is covered with HDPE film (black). Thickness: 4mm,5mm Features: (1) Anti-chloridion impermeability, salinity resistant, alkali resistant, anti-chemical medium corrosion (2) Form high-strength waterproof layer, strong press water resisting ability (3) Good tensile strength, high elongation rate, remarkable adaptivity to the shrinkage, deformation, and crack of the substrate (4) Fine high/low temperature resistance and weather resistance (5) Large-thickness, high-strength PYK, being puncture, break, crack and fatigue resistant (6) Good workability, hot-melt bonding is applicable to any working conditionsApplication Scope: (1) This waterproofing membrane is applied for concrete construction waterproofing work under a corrosion environment. (2) It is widely used in saline, alkaline areas and offshore engineering.
