To show how dose number and dissolution number could be used together to get valuable information, we would have to know another variable called Absorption number [(An).sup.3], which is given by following equation:
Key statement: This invention relates to a rubber composition possessing high wear resistance and low heat buildup, and more particularly to a rubber composition comprising 100 parts by mass of a diene polymer and 20-250 parts by mass of a carbon black as a filler, characterized in that the carbon black has a dibutyl phthalate (DBP) absorption number of 40-180 [cm.sup.3]/100 g, a nitrogen adsorption specific surface area (N2SA) of 40-300 [m.sup.2]/g, a tint strength (TINT) of 50-150% and a light transmittance of toluene extract of not less than 90% and a relation between the nitrogen adsorption specific surface area and the light transmittance of toluene extract satisfies the following equation (I):
The industry named this oil absorption test "DBP," due to the use of dibutyl phthalate oil; however, it is now referred to as an oil absorption number or "OAN." OAN and iodine number are the two target properties used to manufacture and sell carbon black products globally.
