New patent application published for: ELECTRICALLY CONDUCTIVE CARBON BLACK

Electrically conductive carbon black characterized by an oil absorption number ranging from 74 cc/100 g to 114 cc/100 g, a nitrogen surface area ranging from 450 m.sup.2/g to 650 m.sup.2/g, and at least one of a primary particle size distribution ranging from 5 nm to 15 nm, a transmission value at 425 nm ranging from 95% to 100%, or a heat loss ranging from 0 to 12.5%. Elastomeric compositions comprising an elastomer at 100 parts per hundred rubber and the carbon black at loadings from 2 to 25 parts per hundred rubber exhibit enhanced electrical conductivity. Methods for preparing the elastomeric compositions by mixing the elastomer with the carbon black are also provided.
