SIS

SIS

Styrene-Isoprene-Styrene Rubber Properties and Applications. Styrene-isoprene block copolymers (SIS) are large volume, low priced commercial thermoplastic elastomers (TPE) which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. The styrene content typically varies between 15 and 40 percent.

The Difference between Styrene-Butadiene Rubber and .

Styrene-Butadiene Rubber. Styrene-Butadiene Rubber is most often made up of 25% styrene and 75% Butadiene, which is a higher butadiene content than Styrene-Butadiene Latex and this makes it more elastic-like. SB Rubber's development traces back to the discovery of synthetic rubber in Germany in the early 1900s.
