Abstract
The present invention relates to a heterogeneous silica/carbon black-filled rubber compound and a process for making the same. The rubber compound is characterized by containing silica, two different carbon blacks and two different rubbers. One of the carbon blacks is selectively dispersed in one rubber along with the silica and the other carbon black is dispersed in another rubber. The two rubber compounds are then mixed to form a heterogeneous rubber compound.
