Abstract

Novel carbon blacks having a CTAB of from 65 m2/g to 85 m2/g, a DBP of from 130 cc/100 g to 160 cc/100 g, a CTAB/I2 No. ratio of from 1.15 to 1.35, a &Dgr;DPB of from 20 cc/100 g to 40 cc/100 g, a Tint value of from 85 to 100, a Dmode of from 115 nm to 135 nm and a &Dgr;D50/Dmode ratio of from 0.65 to 0.90. Also disclosed are novel rubber compositions, incorporating the carbon blacks, having increased abrasion resistance and lower hysteresis.
