Product Detail

Product Introduction

Styrene-butadiene and styrene-isoprene block copolymers (SBR), also known as styrene-butadiene-styrene (SBS) and styrene-isoprene-styrene (SIS), two related triblock copolymers that consist of polystyrene  blocks at each end of a molecular chain and a butadiene or isoprene sequence in the centre. SBS and SIS are thermoplastic elastomers, blends that exhibit both the elasticity and resilience of butadiene rubber or isoprene rubber (natural rubber) and the ability of polystyrene to be molded and shaped under the influence of heat.
