Abstract:
1. A method for providing a vulcanizable compound, comprising: a) providing a first formula for a rubber composition in which a conventional particulate filler selected from silica, carbon black or a mixture thereof comprises from about 30 to about 100 parts per hundred rubber of said composition; b) identifying a target amount of from about 15 to about 60 weight percent of said conventional particulate filler to be replaced and determining the volume of said target amount; c) identifying at least one particulate filler having an interfacial free energy in water of at least about 300 mJ/m d) determining a weight of said at least one additional particulate filler from step c) that provides a volume that approximately equivalently replaces said volume of said target amount of conventional particulate filler; e) providing a second formula for a rubber composition that employs the particulate filler weight from step (d) in place of said target amount of conventional particulate filler; and f) preparing a rubber composition based on said second formula, thereby providing said vulcanizable compound.
