Styrene-butadiene Rubber 1500

The styrene (alpha-methyl styrene)-butadiene SK(M)S-30 ARK 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 well compatible with different rubbers of general use and needs no special plastification. It has higher strength properties and better metal adhesion.
In mixing with SK(M)S-30 ARKM-27 (SBR-1712) at 1:1 rate the product will be of higher hardness, will grow tyres abrasion resistance and will make bigger its running time up to 10%.
According to its technological properties, processing method and technical characteristics is analogous to the SBR-1500.
