best quality PE filmed torch-on bitumen waterproofing membrane
- Production instruction
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.
Characteristics - Good waterproof performance;
- High tensile and tearing strength, elongation and size stability which accommodates substrate movement and deformation;
- Anti-corrosion, mildew resistant and weather resistant;
- Anti-puncture and rooting resistant, fatigue resistant;
- Hot melt construction, solid and long-lasting;
- 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.
Application
- Roof and underground in industrial and civil buildings;
- bridge, subway, tunnel, swimming pool, etc.
- Waste landfill, sewage plant, irrigation system, etc.
