Elastomer (SBS) modified asphalt waterproofing roll-roofing is a waterproofing material with excellent performance. It is made of styrene-butadiene-styrene (SBS) rubber-modified asphalt as a coating, with a base of glass fibre felt, polyester felt, and glass-fibre-reinforced polyester felt. The material is covered on both sides with isolation materials. It has heat resistance, cold resistance, corrosion resistance, aging resistance, good thermoplasticity, high tensile strength, high elongation, tear resistance, and other advantages.
