Abstract
An NBR composition including an NBR polymer, a vulcanizing agent, a vulcanizing accelerator, and carbon black, wherein the carbon black includes a combination of MT carbon black and carbon black having an iodine absorption number of 20 mg/g or less and a DBP absorption number of 40 cm/100 g or more, and has a total added amount of 110 to 250 parts by weight based on 100 parts by weight of the NBR polymer, and the amount of the MT carbon black is larger than that of the carbon black having an iodine absorption number of 20 mg/g or less and a DBP absorption number of 40 cm/100 g or more and the amount of the carbon black having an iodine absorption number of 20 mg/g or less and a DBP absorption number of 40 cm/100 g or more is 10 to 70 parts by weight based on 100 parts by weight of the NBR polymer, and a metal laminate obtained by laminating the NBR composition.
