SBS 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.
Features:
Good impermeability
Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.
SBS modified bitumen membrane is specially being applied in the cold area with low temperature.
Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering.
