SBR probably is better known under its old
names Buna S and GRS (government rubber styrene.) SBR was
first produced under government control between 1930 and 1950
as a replacement for natural rubber. The basic mono¬mers
are butadiene and styrene, with styrene content approximately
23.5%. About one third of the world output of SBR is used
in tire production. SBR is mostly used in seals for non-mineral
oil based brake fluid applications.
