Modified rubber powders comprising silicatic fillers prepared from precipitation suspensions, process for their preparation and their use

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.
