Abstract
Disclosed is a rubber composition for flexible coupling. In particular, the rubber composition for flexible coupling is prepared by mixing a filler including an HNBR alloy and carbon blacks having different average particle diameters with a hydrogenated acrylonitrile-butadiene rubber such that performance deterioration due to hydrolysis can be prevented even in hot and humid environments and the rubber composition has superior heat resistance and improved mechanical strength.
