Beschreibung
Zusammenfassung:	Disclosed herein are a nitrile rubber composition comprising a nitrile rubber (a) including an ±,²-ethylenically unsaturated nitrile monomer unit and having iodine value of 100 or less, an ±,²-ethylenically unsaturated carboxylic acid metallic salt (b), and silane-treated fumed silica and/or calcinated wet silica (c); a cross-linkable nitrile rubber composition comprising the above nitrile rubber composition and a crosslinking agent (d) ; and a cross-linked rubber obtained by crosslinking the cross-linkable nitrile rubber composition. The present invention can provide a nitrile rubber composition and a cross-linkable nitrile rubber composition, capable of giving a highly-saturated cross-linked nitrile rubber having high tensile stress and excellent heat resistance, and a cross-linked rubber thereof.
