摘要: Described is a free flowing particulate composition comprising, in combination, amorphous precipitated silica, e.g., the form of granules, hydrocarbon process oil, an aromatic and organic carboxylic acid having from 2 to 30 carbon atoms, stearic acid. The oil are sorbed on silica present amounts sufficient measurably improve dispersibility into elastomer as measured by percent white area. Optionally, organosilane coupling agent may also be said composition. invention useful reinforcing elastomers, rubbers used vehicle tires soles athletic foot wear.
