Tires and other rubber goods are employed in many applications that require dynamic deformations and thus the relative amount of energy that is stored or lost as heat during the deformations is important in assessing the performance of the rubber good. While the polymer and different chemicals play a significant role in this, the carbon black is a very important contributor to this balance. Carbon blacks that can impart less energy loss in the form of heat at the same level of reinforcement as a similar carbon black are know as low hysteresis carbon blacks. Carbon blacks have been developed and will be discussed in this paper that exhibit this low hysteresis behavior and represent advanced fillers.
