SBS is a styrene, butadiene, styrene block copolymers formed, its strength is provided by the hard segments of polystyrene (PS), provided by an elastic soft segment of polybutadiene, the merits of both the rubber and plastic , cold resistance, flexibility, elasticity, excellent heat resistance, widely used in footwear, paints, adhesives, light oil, ** devices, household appliances, duct tape, wire and cable, insulation materials, car upholstery material , toys, carpet bottom, furniture and sports equipment and other fields. Styrene - butadiene - styrene block copolymer (SBS) is one of the world's largest output current of thermoplastic elastomers, because of its excellent tensile properties, good low temperature resistance, permeability, solubility and unique The skid resistance [1,2] have been widely used in rubber products, adhesives and asphalt modifier field and resins. SBS is a better polymer modified, respectively, with the PP, PE, PS and ABS resin blends to improve impact resistance, flex products. Application: used in adhesives, sealing materials, shoes, paint, wire and cable sheathing, rubber seal, general commodities, ** or food material molding, jelly candles, candles, transparent, plastic can also be used as a solvent phase ; also widely used in the areas of electrical components, steering wheel, bumper, polymer modified bitumen modification and seals.
