SBS mod bit tensile elongation testing

Revolutionizing Roofing with SBS-Modified Bitumen

Siplast stands out when it comes to SBS-modified bitumen roof system performance. The Siplast story of uncompromising quality and commitment to our customers begins over half a century ago with an innovation that would change the commercial roofing and waterproofing industry. 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 styrene-butadiene-styrene (SBS), we could produce a highly durable elastomeric blend with exceptional elongation/recovery properties over a wide range of temperatures.

Our history of performance has allowed Siplast to complete various tests on the aging characteristics of both its own and competitive SBS-modified bitumen systems. The remarkably consistent quality of Siplast's products provides an extra measure of comfort to building owners. Siplast is the only roofing manufacturer in the United States that can generate a Certificate of Analysis (COA) for all roll roofing material shipped from its manufacturing facility to the job site. The COA provides information on the physical and mechanical performance properties of each Siplast production run, as well as the specific production standards for each property tested. The COA is the building owner's assurance that every roll of Siplast material shipped to the job meets or exceeds Siplast's high standards. Additionally, Certificate of Analysis information can be accessed with Siplast RoofTag.
