Styrene Butadine Styrene

By taking advantage of our huge industrial experience in this sector, we are involved in manufacturing, importing, trading and supplying an extensive range of Styrene Butadine Styrene from Delhi, India. Poly (styrene-butadiene-styrene) or SBS, is a hard rubber that's used to modify asphalt, to make soles of shoes, tire treads, and other places where durability is important. It's a type of copolymer called a block copolymer. Its backbone chain is made up of three segments. The first is a long chain of polystyrene, the middle is a long chain of polybutadiene, and the last segment is another long section of polystyrene.

Polystyrene is a tough hard plastic, and this gives SBS its durability. Polybutadiene is rubbery, and this gives SBS its rubber-like properties. In addition, the polystyrene chains tend to clump together. When one styrene group of one SBS molecule joins one clump, and the other polystyrene chain of the same SBS molecule joins another clump, the different clumps become tied together with rubbery polybutadiene chains. This gives the material the ability to retain its shape after being stretched.
