Styrene Butadiene Rubber 1712, one of synthetic rubber.The aromatic oil used is an efficient plasticizer for high molecular
weight SBR and results in superior physical and processing properties compared to other oil-extended rubbers.
It is used on tires , belts, and other goods compounds where color and staining are not decisive factors.
