摘要：
Carbon blacks having a CTAB of greater than 155 m2/g; an I¿2?No. of greater than 180 mg/g; a N2SA of greater than 160 m?2¿/g; a Tint value of greater than 145 %; a CDBP of 90-105 cc/100 g; a DBP of 115-140 cc/100 g; a ΔDBP (ΔDBP = DBP - CDBP) of 20-35 cc/100 g; a ΔD50 of less than 40 nm; a Dmode of 40-65 nm; ΔD50/Dmode ratio of 0.55-0.67; and an ASTM Aggregate Volume less than 137,000 (nm)3. Also disclosed are rubber compositions containing the carbon blacks which exhibit superior handling and cornering performance properties, increased abrasion resistance and improved traction.
