Rubber composition, and rubber product produced by using the rubber composition

Abstract

An inventive rubber composition contains a rubber component including EPDM, a peroxide crosslinking agent, a white filler, and not less than 0.1 part by mass of a quaternary ammonium salt based on 100 parts by mass of the rubber component. An inventive molded rubber product (1) is made from the rubber composition. Thus, the novel rubber composition containing the rubber component including the EPDM, the peroxide crosslinking agent and the white filler can be imparted with any desired color (e.g., a light color such as white or a non-black color) and can form a molded rubber product excellent in strain resistance properties and the like without inhibition of the crosslinking of the EPDM. The molded rubber product is produced by using the rubber composition.
