torch-on flat roof bituminous waterproof membrane
1. 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.
APP(Atactic Polypropylene) modified bitumen membrane is made by saturating the base in bitumen, or thermoplastics (such as APP, APAO, APO), then covering double faces with thermoplastic elastomer (SBS) and last finishing the upward face with fine sands, mineral slates(or grains)or polythene membrane etc. while downward face with fine sands or polythene membrane.
2.Product Features
Good waterproof performance;
l High tensile and tearing strength, elongation and size stability which accommodates substrate movement and deformation;
l Anti-corrosion, mildew resistant and weather resistant;
l Anti-puncture and rooting resistant, fatigue resistant;
l Hot melt construction, solid and long-lasting;
l 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.Product Application
l Roof and underground in industrial and civil buildings;
l bridge, subway, tunnel, swimming pool, etc.
l Waste landfill, sewage plant, irrigation system, etc.

6. Matters need attention:
1. Don't apply the membrane on the rainy, snowy and windy days.
2. At the construction site, the safety protection facilities must be sufficient, and fire equipments must be effectively placed according to the stipulations.
7. Storage and transportation instruction:
1. When storage and transportation, different types and sizes of products shall be storing separately, not be mixed. And storage temperature should not be over 50 ºC. And the height is only one layer when standing storage.
2. During transportation, the height is not more than two layers.
3. In normal conditions of storage and transportation, storage period is a year since the date of production.
