PROBLEM TO BE SOLVED: To provide a rubber composition capable of improving heat resistance and ozone resistance of a vulcanized material prepared by vulcanizing an epichlorohydrin-based rubber composition, and a vulcanized material.SOLUTION: By incorporating a nickel salt of a dithiocarbamic acid having a ≤2C alkyl group and a copper salt of the dithiocarbamic acid to an epichlorohydrin-based rubber composition, the heat resistance and the ozone resistance of an epichlorohydrin-based rubber material prepared by vulcanizing the composition can be improved. |
