▎ 摘　　要

NOVELTY - Rubber composition comprises rubber component and filler containing carbon black, where the carbon black is chosen from conductive carbon and graphene, the content of the carbon black is 58-125 parts mass with respect to 100 parts mass rubber components, the thermal conductivity of the rubber composition is 0.40 W/m.K or more, and the stress at 300% elongation of the rubber composition at 150 degrees C is 2.8 MPa or more. USE - The rubber composition is useful for producing vulcanized bladder (claimed) which is used when manufacturing tire. ADVANTAGE - The rubber composition exhibits excellent durability and vulcanization production efficiency.
