self adhering modified bitumen roofing sheet for underground waterproofing
1. Production Introduction:
SBS(Styrene Butadiene Styrene) modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforced with polyester or fiberglass, finishing the upward face with fine sands, mineral slates (or grains) or polythene membrane etc.
2. Characteristics:
1) Good waterproof performance;
2) High tensile and tearing strength, elongation and size stability which accommodates substrate movement and deformation;
3) Anti-corrosion, mildew resistant and weather resistant;
4) Anti-puncture and rooting resistant, fatigue resistant;
5) Hot melt construction, solid and long-lasting;
6) SBS modified bitumen membrane is specially applied in the cold district, while APP modified bitumen membrane is more suitable for hot district with high temperature.
3. Application:
1) Roof and underground in industrial and civil buildings;
2) bridge, subway, tunnel, swimming pool, etc.
3) Waste landfill, sewage plant, irrigation system, etc.
