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