Abstract: A novel carbon black can improve rubber properties (e.g., degree of reinforcement and heat buildup). The carbon black has an aggregate void modal diameter Dmp determined by mercury porosimetry of 25 to 60 nm, and has a ratio (ΔDmp/modal diameter Dmp) of a half-width ΔDmp of an aggregate void diameter distribution determined by mercury porosimetry to the aggregate void modal diameter Dmp of 0.30 to 0.56.

Abstract: Carbon black is used as a component of a rubber composition, ensures that the resulting rubber exhibits improved processability, is reinforced in an improved manner, and exhibits low heat buildup, and may suitably be used for a rubber member (e.g., tire tread) and the like for which high abrasion resistance is required. The carbon black includes primary particles having an average particle size of 15 to 35 nm, and forms aggregates having a Stokes mode diameter measured using a centrifugal sedimentation method of 140 to 180 nm, and having a spherical shape when observed using a transmission electron microscope.
