ABSTRACT:
An elastomer composition is prepared that contains a rubber component (A) containing at least one of diene rubber and EPDM rubber; a mixture composition (B) containing hydrogenated styrene thermoplastic elastomer and olefin resin; and a styrene thermoplastic elastomer (C) having double bonds partly left, wherein the styrene thermoplastic elastomer (C) is blended at a ratio of not less than 2 parts by weight and not more than 100 parts by weight with respect to 200 parts by weight of the mixture composition (B), and the rubber component (A) is dispersed by dynamic crosslinking in the mixture composition (B) having the styrene thermoplastic elastomer (C) dispersed therein. A rubber roller is formed by using the elastomer composition. The elastomer composition is excellent in wear resistance, and the rubber roller made of the elastomer composition is excellent in wear resistance at the time of idling rotation.
