Suggested is a carbon black composition showing a narrow Aggregate Size Distribution (ASD) characterized by a &#x394;D/Dvalue of about 0.58 to about 0.65 and a Relative Span (D&#x2212;D)/Dof about 0.5 to about 0.8, which is obtainable by means of a modified furnace reactor. The composition shows superior additive performance and allows producing e.g. bus or truck tires with improved wear resistance and reinforcement.

Carbon black compositions

The invention relates to a carbon black with a CTAB surface area of from 20 to 49 m/g, with a COAN greater than 90 ml/(100 g), and with a sum of OAN and COAN greater than 235 ml/(100 g). The carbon black is produced in a furnace reactor, where from 20 to 55% by weight of the feedstock used for the carbon black are introduced radially through a nozzle within the first third of the reaction zone, and the remaining amount of the feedstock used for the carbon black is introduced through a nozzle upstream at least one further point into the reactor. The carbon black can be used in rubber mixtures.
