Carbon black beads are provided which generally comprise carbon black powder and an elastomer such as styrene butadiene rubber, butadiene rubber, natural rubber, nitrile rubber, or the like, in an amount between 0.5 and 5.0% by weight of the beaded carbon black. The carbon black beads are made by beading the carbon black powder with latex. The latex treated carbon black is readily handleable in bulk form, easily dispersible in elastomeric compositions, and imparts improved dynamic properties to elastomeric compositions.
