Nitrile rubber composition, vulcanizable nitrile rubber composition, and vulcanizate

Abstract

A vulcanizable nitrile rubber composition comprising 100 parts by weight of a nitrile rubber, 0.1 to 20 parts by weight of a metal silicate and 0.1 to 10 parts by weight of a vulcanizing agent. Vulcanization of this vulcanizable rubber composition gives a vulcanizate exhibiting enhanced heating aging resistance when it is kept in a hot air atmosphere, especially at a high temperature.
