Description

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 heating the material can flow, easy processing molding . After cooling to room temperature, the polystyrene segments 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.
Appearance: SBS is white or yellowish porous round or disk-shaped particles, the relative density of 0.*2 to 0.*5.
SBS has excellent tensile strength, elasticity and electrical properties, permanent deformation is small, good flexion and rebound, the surface friction. But the SBS anti-aging is poor.
