Acrylic rubber composition which comprises an acrylic rubber having a carboxyl group in the molecule, a vulcanizing agent and a vulcanization accelerator and use thereof

摘要

It is superior in can stability before the vulcanizing, when vulcanizing burning is difficult to occur, vulcanization ones which are obtained the compression permanent deformation are small, it designates that the acrylic rubber composition whose change of the physical properties with heating is small is offered as purpose. The polyamine compound (B) 0.05 - 5 weight sections, 0.1 - 10 weight sections and 0.1 - 8 weight sections containing chiuramu chemical compound (D), the acrylic rubber composition and its utilization which become are offered guanidine chemical compound (C) vis-a-vis the acrylic rubber (A)100 weight section which possesses the carboxyl group inside the molecule.
