Characteristic a)Good impermeability
b)SBS modified bitumen membrane is specially being applied in the cold area with low temperature c)Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering
d)Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.
Suitable for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproof, especially for the building under high temperature. According the roofing engineering stipulation, APP modified bitumen membrane could be used in the Grade I civil building and industrial building which has special waterproofing requirement
