Disclosed is a hydrogenated NBR composition comprising 100 parts by weight of a hydrogenated NBR having an acrylonitrile content of 25 to 44% by weight and an iodine value of 32 to 65 or a blend of hydrogenated NBRs each having the same properties as mentioned above, 2 to 23 parts by weight of an ester-type plasticizer and 0.5 to 10 parts by weight of an organic peroxide, preferably further containing 0.5 to 10 parts by weight of a polyfunctional unsaturated compound. The hydrogenated NBR composition is excellent in heat resistance, cold resistance, oil resistance and fuel oil resistance and can be therefore used suitably as a molding material for an intake manifold gasket in an automobile engine or the like.
