Synthetic Rubber / SBR1712
SKS-30 ARKM-27 is a staining type cold SBR. Raw materials for this elastomer are carefully chosen to produce the best physical properties and processing characteristics. The dark coloured staining type oil used, possesses a higher level of plasticizer rubbers. Choice of this more efficient plasticizer results in a polymer having superior physical and processing properties compared to other oil-extended rubbers. This product is used in the manufacture of tires, camel-back and mechanical goods compounds, where colour and staining are not decisive factors.
