[Object] To provide: an acrylic rubber composition, which is improved in roll tackiness upon processing and in dough-like-material tackiness between dough-like materials themselves, and which is remarkably improved in processing characteristic, without deteriorating resultant normal physical properties; and an acrylic rubber composition molded and used for a sealing part such as an O-ring, gasket, and packing. [Solving means] An acrylic rubber composition comprising 100 parts by weight of an ACM polymer, which contains monomers each having a carboxyl group(s) as crosslinking-site monomers, respectively, and 5 to 30 parts by weight of vein graphite or flake graphite; and an acrylic rubber composition comprising 100 parts by weight of an ACM polymer, which contains monomers each having a carboxyl group(s) as crosslinking-site monomers, respectively, 5 to 30 parts by weight of vein graphite or flake graphite, and 0.5 to 1.5 parts by weight of a liquid paraffin. |
