Abstract
A cross-linkable nitrile rubber composition including a highly saturated nitrile rubber (A) containing α,β-ethylenically unsaturated nitrile monomer units in a ratio of 10 to 60 wt % and having an iodine value of 120 or less, a master batch (B) containing an ethylene-vinyl acetate copolymer (b1) having a melt flow rate measured under a load of 21.18N at 190° C. of 0.5 to 1000 g/10 min. and containing vinyl acetate monomer units in a ratio of 5 to 50 wt % and an organic staple fiber (b2) having an average fiber length of 0.1 to 12 mm, and a cross-linking agent (C), wherein a ratio of the ethylene-vinyl acetate copolymer (b1) and the organic staple fiber (b2) in the master batch (B) is, in terms of a weight ratio of 'ethylene-vinyl acetate copolymer (b1):organic staple fiber (b2)', 30:70 to 80:20 is provided.
