Abstract

The present invention provides a rubber composition, which realizes low hardness and low compression set while maintaining semi-conductivity, and a vulcanizate thereof. Also the rubber composition can be obtained by blending an epichlorohydrin-based rubber having satisfactory semi-conductivity and an acrylonitrile-butadiene-based rubber as a reactive plasticizer, and also blending zinc oxide, a thiuram-based compound and a quinoxaline-based compound.
