Multi-Ply SBS-Modified Bitumen Systems

Multi-Ply SBS-Modified Bitumen Systems

Multi-Ply SBS-Modified Bitumen Systems In the late 1960s, Siplast Research and Development, working in conjunction with Shell Chemical of Europe, developed SBS (styrene-butadiene-styrene) modified bitumens. We found that by properly modifying asphalt with SBS, we could produce a highly durable elastomeric blend with exceptional elongation and recovery properties over a wide range of temperatures. This technology was applied to the design of our two-ply engineered roof systems, in which the workhorse base ply absorbs roof stresses while the top ply shields the base from the elements and mechanical abuse.
