PURPOSE:To provide a rubber composition containing a silicone rubber and a hydrogenated nitrile rubber as a base, having increased mutual dispersibility of both rubber components and improved roll-processability of unvulcanized rubber composition and giving a cross-linked rubber having improved tensile strength, thermal aging resistance, cold-resistance and oil-resistance. CONSTITUTION:The objective rubber composition is principally composed of (A) 2-98wt.% of a hydrogenated nitrile rubber containing carboxylic acid group or epoxy group and (B) 98-2wt.% of an organopolysiloxane having functional group reactive with the functional group of the component A. |
