Elastomer composition comprising a blend of SBR rubbers

摘要

A rubber composition having improved rolling resistance and wet grip characteristics with improved processability, abrasion resistance and durability which contains as a rubber component a mixture of a high molecular weight styrene-butadiene rubber having a specific microstructure and a low molecular weight styrene-butadiene and/or butadiene rubber having a specific microstructure. The composition is particularly suitable for use in tread of tires.
