Styrene-Butadiene-Styrene (SBS) describes a family of synthetic rubber derived from styrene and butadiene. SBS is a thermo plastic elastomer that has an excellent abrasion resistance and aging stability when blended with bitumen, making it the perfect bitumen modifier to achieve cold flexibility and elastic properties.
Benefits of an SBS Roof
SBS rubber is flexible and has the memory to return to its original form. The addition of SBS rubber to asphalt increases the flow characteristics and improves the low-temperature flexibility and fatigue resistance of roofing asphalt. The end product is a high-performance, 2-3 ply system.
