PURPOSE: A carbon black having low tensile stress, high elongation and tensile strength and improved extrusion property is provided by keeping up a volume of iodine absorption, oil absorption volume of dibutyl phthalate, coloring degree, toluene coloring permeability and a ratio of aggregation size distribution. CONSTITUTION: Carbon black is provided which has volume of iodine absorption less than 50 mg/g, oil absorption value of dibutyl phthalate less than 150 cc/100 g, coloring degree less than 60%, 2.57- 4.35 ratio of the volume oil absorption value of dibutyl phthalate and the ratio of iodine absorption, 60-95 % of toluene coloring permeability, 1.15-1.40 ratio of oil absorption value of dibutyl phthalate and compressed dibutyl phthalate, 20.67-40.20 of structure index and 1.85-2.00 of aggregate size distribution ratio. |
