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.
Claims8
A rubber composition for a semi-conductive vulcanization, comprising, based on 100 parts by weight of a blend rubber comprising (a) 50 to 90% by weight of an epichlorohydrin-based rubber and (b) 10 to 50% by weight of an acrylonitrile-butadiene-based rubber, (c) 0.1 to 5 parts by weight of a thiuram-based compound, (d) 1 to 10 parts by weight of zinc oxide and (e) 0.1 to 5 parts by weight of a quinoxaline-based compound.
