Particulate silicas are made by precipitation from aqueous solution. The physical and chemical properties of precipitated silicas can vary according to the manufacturing process. Due to the small particle size and complex aggregate structure , precipitated silica imparts the highest degree of reinforcement to elastomer compounds among all the non-black particulate fillers.
