Hydrogenated styrene-butadiene block copolymers (SEBS), SEBS series hydrogenated butadiene block copolymers are thermoplastic elastomers prepared by hydrogenation on the basis of Zhongli SBS. It has the characteristics of low temperature resistance, aging resistance and high elasticity. Through special structural design and polymerisation method, SEBS series products have better compatibility with polyolefin, polystyrene, nylon and other polymer materials. Hydrogenated styrene-butadiene block copolymers are widely used in plastic modification, sealing materials and medical products.
