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.

Carbon black, method for the production thereof, and use thereof

The invention relates to black having a CTAB surface area of 100 to 160 m?/g, a quartile ratio of more than 1.60, and an FP index of &#x3e;0. Said black is produced in a furnace reactor. Sixty to 90 percent by weight of the raw black material are injected into the reactor in the first third of the reaction zone, while the remaining amount of the raw black material is injected into the reactor upstream at least in one other point. In addition, the combustible is conducted such that 90 to 100 percent by weight of the combustible are evaporated when first hitting the raw black material and 80 to 99 percent by weight of the combustible are evaporated 5 ms before hitting the raw black material. Said blacks can be used in rubber mixtures.
