Styrene Isoprene Styrene (SIS) is also termed, as styrene-isoprene block copolymers (SBR) are the thermoplastic elastomers that have both the resilience and elasticity of isoprene rubber. Moreover, it has an ability of polystyrene to be molded and shaped under the effect of heat. They are known to have low-temperature durability, high strength, and excellent elasticity. On the other hand, these are non-polar polymers containing low resistance to hydrocarbon oils or many solvents. Más
