SEBS (Styrene Ethylene Butylene Styrene) sebs is a linear triblock copolymer with polystyrene as the terminal segment and ethylene butene copolymer obtained by hydrogenation of polybutadiene as the intermediate elastic block. SEBS has good UV stability, oxygen resistance, and thermal stability, so it can also be used in asphalt for roofs and road construction. SEBS has good compatibility with paraffin, so it can be used as a flexible surface coating for paper products. SEBS does not contain unsaturated double bonds, therefore it has good stability and aging resistance
