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 facewith fine sands, mineral slates (or grains) or polythene membrane, etc.
APP The products are made by soaking the base thermoplastics (such as a tactic polypropylene-APP,APAO.APAL) modified bitumen, then covering double faces with elastomeric (SBS)or thermoplastics (APP,APAO,APAL)modified bitumen, and last finishing the upward face with fine sands, mineral slates or polythene membrane etc. While downward face with fine sands or polythene membrane, It has good waterproofing and ageing-resistance function, not flowing at highest temperature and no crack at lowest temperature; easy application, no pollution, and long service life, etc .APP modified bitumen waterproof membrane is specially suitable to the building waterproofing in cold area and to the buildings of changeable constructions, while APP specially suitable to high temperature and strong sun-shining.
1. Good impermeability.
2. Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.
3. Good performance in anti-puncture, anti-broken, anti-resistance, anti-erosion, anti-mildew, anti-weathering.
4. Construction is convenient, the melt method can operate in four seasons, joints are reliable
5. It has good waterproofing and ageing-resistance function, not flowing at highest temperature and no crack at lowest temperature; no pollution, and long service life, etc.
1) Roof and underground in industrial and civil buildings;
2) bridge, subway, tunnel, swimming pool, etc.
3) Waste landfill, sewage plant, irrigation system, etc.
SBS modified bitumen membrane is specially applied in the cold area with low temperature.
APP modified bitumen membrane is specially applied in the hot area with high temperature.
1. When storage and transport, different types, specifications of the products shall be separately to each other, should not be mixed. Storage temperature should not higher than 50 degree, stand up storage, a height of not more than two layer.
2. In the normal storage, transport conditions, storage period since the production date for a year.
