SBS APP modified bitumen waterproof membrane
The products are made by soaking the base in bitumen, or thermoplastic elastomer(Such as styrene butadiene-SBS),or thermoplastics(Such as atactic polypropylene-APP,APAO,APAL)modified bitumen, then covering double faces with elastomer(SBS)or thermoplastics(APP,APAO,APAL)modified bitumen, and last finishing the upward face with fine sands, mineral flakes(or Grains) or polythene membrane etc. while downward face with fine sands or polythene membrane.
Features
Good ability of anti-aging, anti-alkali, resistant to high temperature. High tensile strength and elongation, which adapts to the contraction or crack of the base
non-toxicity,odourless,non-pollution and good flexibility
Application:
1, Basement and roofing of key waterproof engineering , general and civil engineering . Such as planting roof, flat roof and sloping roof.
2, Bridge , grain depot, road, granary, tunnel, park ,swimming pool, sewage purifying pool landfill and others.
3, Especially adapting to the area with strong sunshine or high temperature.
