Carbonaceous material with dissociated aggregate size and particle size distribution and improved dispersibility

摘要

The present invention claims that a carbon black with unique morphological properties provides improved carbon black dispersion and improved rubber compound properties, such as improved fatigue life and abrasion resistance. The carbon black of current invention has a ratio of aggregate size HI and particle size HI greater than 1.70, the surface area STSA of 100-180 M2/g and the structure OAN less than 140 cc/100 g.
