Buna-S (SBR)

Whether you call it Buna-S, Styrene Butadiene Rubber (SBR), or Government Rubber Styrene (GRS), this was the elastomer substituted for Natural Rubber between 1930 and 1950, mostly as result of a shortage due to World War II.  About a third of the output of SBR is used in tire production.
