Abstract

A highly saturated nitrile rubber composition containing a carboxyl group-containing highly saturated nitrile rubber (A1) which contains α,β-ethylenically unsaturated nitrile monomer units 15 to 60 wt % and α,β-ethylenically unsaturated dicarboxylic acid monoester monomer units 1 to 60 wt % and has an iodine value of 120 or less, a highly saturated nitrile rubber (A2) which contains α,β-ethylenically unsaturated nitrile monomer units 15 to 60 wt %, has a content of the α,β-ethylenically unsaturated dicarboxylic acid monoester monomer units of 0.9 wt % or less, and has an iodine value of 120 or less, and a polyamide resin (B), a content ratio of the carboxyl group-containing highly saturated nitrile rubber (A1) and the highly saturated nitrile rubber (A2) being a weight ratio of 'carboxyl group-containing highly saturated nitrile rubber (A1):highly saturated nitrile rubber (A2)' of 2:98 to 98:2, is provided.
