Copolymer G/Hydrogenated Styrene Butadiene Block Copolymer
产品概述

Hydrogenated styrene-butadiene block copolymer is a polymer prepared by copolymerization of two monomers, hydrogenated styrene and butadiene, in a certain ratio. It has a homogeneous molecular structure in which the two blocks of hydrogenated styrene and butadiene are arranged alternately in a specific arrangement. This copolymer has excellent thermal stability, weather resistance and mechanical properties, and is widely used in plastics, rubber, adhesives and other fields.
