Abstract

Suggested is a carbon black composition showing a narrow Aggregate Size Distribution (ASD) characterized by a ΔD50/Dmode value of about 0.58 to about 0.65 and a Relative Span (D90−D10)/D50 of 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.
