Abstract
A functionalized silica product includes particles of a hydrophobated silica having a thin coating of an emulsion polymer. A ratio of the hydrophobated silica to the emulsion polymer is from about 4/1 to about 50/1. The functionalized silica product is in the form of a friable crumb or a powder that may be mixed into a elastomer formulation for a rubber article, such as a tire component.
