<p>Sealing members, such as rolling bearing seal and oil seal, which are not only satisfactory in the fundamental properties erequired of them, such as sealing performance, heat resistance, mechanical strength and oil resistance, but also excellent in creep and PAG resistances. The member has an elastic part and is made by molding a modified nitrile rubber comoprising a butadiene-acrylonitrile-acrylate copolymer and containing an organic peroxide as a vulcanizer, a metal oxide as a vulcanization aid, and a basic silicate as a reinforcing filler.</p> |
