A nitrile rubber composition which contains a carboxyl group-containing nitrile rubber (A), a liquid nitrile rubber (B), and a polyamine-based cross-linking agent (C) is provided. In the nitrile rubber composition of the present invention, preferably the carboxyl group-containing nitrile rubber (A) has an iodine value of 120 or less. Further, in the nitrile rubber composition of the present invention, preferably the carboxyl group-containing nitrile rubber (A) contains ±,²-ethylenically unsaturated nitrile monomer units 5 to 60 wt%, carboxyl group-containing monomer units 0.1 to 20 wt%, and conjugated diene monomer units 15 to 94.9 wt%. |
