SBS-Modified Bitumen
Revolutionary styrene-butadiene-styrene (SBS) modified bitumens were pioneered by Siplast in partnership with Shell Chemical of Europe in the late 1960s. This technology formed the basis of Siplast's core high-performance, two-ply engineered roof systems — Paradiene and Veral — creating trusted solutions that have become a mainstay for commercial building projects.
