HSR HS-68
Product Overview
High Styrene Rubber (HSR) is a specialized variety of styrene-butadiene rubber characterized by its high styrene content. It is a non-polar polymer prepared through emulsion copolymerization of styrene and butadiene monomers. HSR is also known as hard rubber due to its enhanced hardness properties compared to conventional styrene-butadiene rubber.
