Styrene-Butadiene Block Copolymer (SBS), SBS series products are styrene thermoplastic elastomers synthesised by a special polymerisation process using styrene and butadiene as monomers. It combines the plasticity of plastic and the elasticity of rubber. Styrene-butadiene block copolymer (SBS) has the advantages of high surface friction coefficient, low temperature resistance and easy processing. It is widely used in asphalt modification, polymer modified adhesives and other fields.
