SEBS is a linear triblock copolymer with polystyrene as the end segment and ethylene butene copolymer obtained by hydrogenation of polybutadiene as the intermediate elastic block. SEBS does not contain unsaturated double bonds, so it has good stability and aging resistance. It is both plastic and highly elastic and can be processed and used without vulcanization. The leftover materials can be reused and are widely used in the production of high-end elastomers, plastic modifiers, adhesives, lubricating oil tackifiers, etc Filler and sheath materials for wires and cables.
