Styrene-butadiene Rubber 1502

The styrene (alpha-methyl styrene)-butadiene SK(M)S-30 ARKPN Rubber is produced by emulsion copolymerization of styrene and butadiene at 4 C 8 C. The mixture of soaps of disproportionated rosin and synthetic fatty acids 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 quite compatible with different rubbers of general use and needs no special plastification.
According to its technological properties, processing method and technical characteristics is analogous to the SBR-1502.
