U.C.C.L. STYRENE BUTADIENE RUBBER (SBR 1502).
The styrene-butadiene Rubber is produced by emulsion copolymerization of styrene and butadiene at 4-8°C. The mixture of soaps of disproportionated rosin and synthetic fatty acid is used as emulsifier.
It is well mixing with different ingredients of rubber compounds and is easily treated on the simple rubber production equipment, is quiet compatible with different rubbers of general use and needs no special plastification.
