SBS is the largest yield of SBCs (accounting for more than 70%), the lowest cost, a wide range of applications, based on styrene, butadiene as a monomer triblock copolymer, both plastic and rubber characteristics, known as the "third generation of synthetic rubber." Similar to styrene butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc., with excellent tensile strength, large surface friction coefficient, good low temperature performance, excellent electrical properties, good processing properties and other characteristics, becoming the largest consumption of thermoplastic elastomer.
