These "triblock" copolymers, also known as styrene butadiene styrene (SBS), consist of polystyrene sequences (or blocks) at each end of the chain and a butadiene or isoprene sequence in the centre. Styrene butadiene styrene is used widely in pneumatic tires, shoe heels and soles and gaskets. Styrene butadiene styrene is a commodity material which competes with natural rubber. Styrene butadiene styrene has good physical properties and excellent abrasion resistance. For these reasons styrene butadiene styrene is the base of a wide range of products and Goldenplast uses styrene butadiene styrene since years.
