Abstract: A process for preparing silica-filled rubber powder is provided, which includes contacting a salt-containing silica-precipitation suspension with at least one selected from the group including a rubber latex, rubber solution, and rubber emulsion, to form a mixture; and precipitating to produce a silica-filled rubber powder. A silica-filled rubber powder prepared by the process, and compositions and uses containing the same, are also provided.

Abstract: Fine-particle, filled rubber powders prepared by precipitation from aqueous mixtures of a filler suspension and a rubber-latex emulsion in the absence of water-soluble salts of metals of groups IIa, IIb, IIIa, or VIII of the Periodic Table of the Elements and in the absence of alkali metal silicate are used for vulcanizable rubber mixtures.
