<p>Carbon blacks having a nitrogen surface area (N2 SA) of from at least 180 m2/g to about 250 m2/g, a ratio of nitrogen surface area/iodine adsorption number (N2 SA/I2 No.) of from about 0.90 to about 1.05, a ratio of DELTA D 50/Dmode of from about 0.67 to about 0.81, a DBP (dibutyl phthalate number) of from about 115 cc/100 g to about 135 cc/100 g and a DELTA DBP [ DELTA DBP=DBP-CDPB (Crushed DBP)] less than or equal to 20 cc/100 g, and rubber compositions in which the carbon blacks are incorporated.</p> |
