Novel carbon blacks having a CTAB of from 65 m /g to 85 m /g, a DBP of from 130 cc/100 g to 160 cc/100 g, a CTAB/I 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;D /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.

Carbon black and rubber compositions containing same

New carbon blacks that when incorporated into rubber compositions impart increased abrasion resistance and lower hysteresis. Also disclosed are rubber composition incorporating the novel carbon blacks, which have nitrogen surface area of at least 100, a CDBP of at least 105, a tint of 90-140 and a delta D50/Dmode ratio of 0.6-0.76.

Carbon black and rubber composition containing same

Carbon blacks having stable surface area and structure which, when incorporated into rubber compositions, impart increased abrasion resistance and lower hysteresis. Also disclosed are rubber composition incorporating the novel carbon blacks.

Carbon black having a high specific surface area

Carbon blacks having an I.sub.2 number of 135-200 and a DBP of 105-150 which, when incorporated into rubber compositions, impart increased abrasion resistance and lower hysteresis. Also disclosed are rubber compositions incorporating the novel carbon blacks.

Carbon blacks having a N.sub.2 SA of from at least about 150 m.sup.2 /g to about 180 m.sup.2 /g, a DBP of about 125 cc/100 g or less, a Dmode of 70 nm or less, a N.sub.2 SA/I.sub.2 No. ratio of 0.85 to 0.98 and a .DELTA.DBP less than 210 cc/100 g which, when incorporated into rubber compositions, impart increased abrasion resistance, heterogenous abrasion resistance and grip performance properties. Also disclosed are rubber composition incorporating the novel carbon blacks.
