Abstract
An acrylic rubber composition comprising 0.05 to 3.0 parts by weight of a fluorine-containing compound having a melting point of 30 to 100° C., based on 100 parts by weight of acrylic rubber. The acrylic rubber composition that can improve the dispersibility of a processing aid in the compound and the rubber compound handling properties during open roll operation without using a silicone-based processing aid, which causes bleeding of vulcanizates, and that satisfies the various characteristics, such as dimensional stability and heat resistance, of vulcanizates.
