Provided are a blended rubber, from which a vulcanizate having high wear resistance and high ozone resistance can be obtained, a blended rubber composition, and a vulcanizate obtained from the blended rubber composition. The blended rubber comprises 30-93 mass% of a chloroprene rubber, 5-50 mass% of flexible polyvinyl chloride and 2-20 mass% of an acrylonitrile butadiene rubber. It is preferred to use a polyvinyl chloride resin having a polymerization degree of 300-3000. Also, it is preferred that the acrylonitrile content of the acrylonitrile butadiene rubber is 18-50 mass%. |
