AZODICARBONAMIDE TREATMENT FOR CARBON BLACK AND RUBBER COMPOUNDS

摘要

A process for producing cured rubber is disclosed wherein the process comprises: A) mixing rubber, carbon black, and azodicarbonamide without other curative ingredients; B) adding the remaining curative ingredients in one or more subsequent mixing steps; and then C) curing the rubber; whereby a cured rubber having improved hysteresis is obtained. The cured rubber thus obtained is particularly useful in tires and tire treads.
