Provided is a nitrile-group-containing highly saturated copolymer rubber composition formed comprising: a nitrile-group-containing highly saturated copolymer rubber (A) having a Mooney viscosity [ML1+4,100°C] of 50-200; a nitrile-group-containing highly saturated copolymer rubber (B) having a Mooney viscosity [ML1+4,100°C] of 5-45; and short fibres (C) having an average fibre length of 0.1-12mm. The present invention enables the provision of a nitrile-group-containing highly saturated copolymer rubber composition which can provide crosslinked rubber having extremely high tensile strength and excellent low heat generation properties, and which has excellent workability. |
