Abstract
(EN)
Provided are: a rubber composition containing a peroxide-crosslinked hydrogenated nitrile rubber, the rubber composition having improved scorch stability without compromising the excellent properties of a crosslinked product of the composition; and a crosslinked product of the composition. The rubber composition contains 100 parts by mass of a hydrogenated nitrile rubber (A), 5-100 parts by mass of a filler (B), 1-10 parts by mass of an organic peroxide (C), and 1-20 parts by mass of a liquid diene-based rubber (D) having a polystyrene equivalent weight average molecular weight of 3,000-120,000 as measured by gel permeation chromatograph (GPC).
