Abstract: This invention relates to a light weight rubber blend that can be beneficially used in rubber articles, such as power transmission belts and tires. In the rubber blends of this invention a 2:1 layered silicate clay, preferably an organophilic 2:1 layered silicate clay, is substituted for a portion of the carbon black that is normally used in the rubber as a filler. This can be done without sacrificing the physical properties of the rubber composition in cases where the rubber in the blend contains an amino group. Tire tread compounds that utilize such rubber compositions offer increased vehicle fuel economy. This invention also relates to improving the strength, modulus and elongation of carbon black and silica filled compounds by the addition of 2:1 layered silicate clays thereto without modifying the level of carbon black or silica. Such compounds have increased flexibility and tensile strength for tire side-wall applications.
