An Introduction to the Industry Leader in SBS-modified Bitumen

For more than 35 years, Siplast has been a leader in the development and manufacture of the world's most advanced roofing and waterproofing systems. A member of the Icopal Group, one of the world's largest commercial roofing manufacturers, Siplast has a history of innovation. 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/recovery properties over a wide range of temperatures.

There are Siplast roofs applied in the early years of our SBS blend that are still in service today. Since then, Siplast Engineered Roof Systems have been applied over all types of deck constructions, in the extremely varied weather conditions of more than 40 countries. Over the years, Siplast SBS-modified bitumen roofs have changed the least, lasted longer, and performed better than anyone else's.
