Sinopec SBS Thermoplastic Elastomer styrene-butadi

Product Details

SBS

SBS thermoplastic elastomer: is styrene - butadiene - styrene three segment copolymer, also known as thermoplastic styrene butadiene styrene block copolymer or thermoplastic, referred to as SBS.After cooling to room temperature,the polystyrensegments
aggregate into a glassy microdomain, which acts as a physical cross-linking point for the polybutadiene segments, thereby rendering the material behaving as rubber. So called thermoplastic elastomer". Depending on the synthesis method, the SBS has a linear structure and a star structure
