SEBS YH-602T is a star-shaped triblock hydrogenated styrene-butadiene copolymer, classified as a general-purpose SEBS powder featuring medium-to-high flow, high oil absorption, and high resilience. Produced via selective hydrogenation of SBS, the degree of hydrogenation for the polybutadiene block double bonds in its molecular chain reaches ≥97%, structurally eliminating common SBS drawbacks such as susceptibility to oxidation, yellowing, and poor weatherability.
