Product Profile Precipitated silica is silica produced by precipitation. Precipitated Silica is a versatile inorganic chemical which is used for reinforcement of rubbers and plastics, thickening and thixotropy of coating and paints, printing inks and cosmetics, antiblocking of plastic foils, free running and free flow of sticky solid and liquid substances, carrier for pesticides, insecticides, high temperature insulation, stabilizing of beer and silicon rubber. It imparts good finish, strength and balances at the required physico- chemical properties of the products. Product characteristics Appearance : White free flowing powder or lumps Water absorption value: 250% minimum Oil absorption value : 225% min. Moisture at 1100 C : 5-7 % Silica content SiO2: 88-90% Applications Precipitated silica is useful to enhance bond strength and as a reinforcing and thickening agent. Silica provides thixotropy, reinforcement and promotes adhesion as well as serves as extenders; therefore it raises quality and lowers cost. Silica prevents resin separation and the settling of pigments and heavy fillers. Precipitated silica has industrial applications in rubberized foot wear, paint, dyes, printing ink, and plastic products. Precipitated Silica is used to improve the tear strength due to its small particle size and complex aggregate structure. Precipitated Silica is used to improve pigment dispersion and acts as a parting agent and as absorbent to improve the flow and imparts a dry feel to the compound. Precipitated Silica is used in Railway Pads because it provides increased abrasion resistance and strength. In industrial rubber, precipitated silica confers superior strength and durability on industrial Rubber Belts and Rubber Hoses together with improved heat resistance and tear strength. Production Process The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid. Sulfuric acid and sodium silicate solutions are added simultaneously with agitation to water. Precipitation is carried out under alkaline conditions. The choice of agitation, duration of precipitation, the addition rate of reactants, their temperature and concentration, and pH can vary the properties of the silica. The formation of a gel stage is avoided by stirring at elevated temperatures. The resulting white precipitate is filtered, washed and dried in the manufacturing process. Na2(SiO2)3.3(aq) + H2SO4(aq) ? 3.3 SiO2(s) + Na2SO4(aq) Market scenario The present demand for precipitated silica is estimated at 166.83 tonnes per annum. The demand is expected to reach at 402.03 tonnes by the year 2020. Precipitated silica is manufactured in India both in medium and small scale sector. Indian production is around 70,000 tonnes per annum.
