Novel carbon blacks having an I2No. of 26-34 mg/g; a CTAB of 26-34 m2/g; a Tint of 46-54%; a DBP of 61-69 cc/100 g and a Dst/Dmode ratio of 1.31-136. Preferably the carbon blacks are additionally characterized by having a Number Median (Dc/Dp) of 2.7-3.1. Also disclosed are novel rubber and plastic compositions which, when the novel carbon blacks are incorporated therein, have lowered viscosity properties during subsequent processing. |
