Sinopec Qilu Chemical SBR1712
SBR1712 , 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.
