SBS modified bitumen waterproof membrane

タイトルまたは説明

SBS modified bitumen waterproof material is atactic polypropylene (SBS), high polymer, other chemical material and asphalt at high temperature by use of strict technology and scientific formulation .And then use polyester unwoven fabric as fabric layer , with evenly impregnated double sides to make SBS modified asphalt composite , a new type waterproof material the surface of which undergoing a technological process ***** covering it with PE film , fine sand and slate separately. 　　SBS modified bitumen waterproof material has a good non-water permeability .A long life in use , low cost , a relatively high tensile strength and coefficient of elongation and good performance of high and low temperature resistance. 　　SBS modified bitumen waterproof material has a good non-water permeability .A long life in use , low cost , a relatively high tensile strength and coefficient of elongation and good performance of high and low temperature resistance.
