ABSTRACT:
A carbon black with a tint residual below -6 in a rubber composition causes the hysteresis or heat buildup of such a rubber composition to be significantly lower than that of a rubber composition incorporating a carbon black with a higher tint residual, while the abrasion resistance of such rubber compositions incorporating these different blacks remains essentially unchanged. Tint residual is the difference between the measured tint and the tint calculated from the structure, nitrogen surface area, and CTAB surface area in accordance with a specific formula disclosed.
