Precipitated Silica CAS#7631-86-9
Great Dispersion Ability: This precipitated silica has fine uniform particles, disperses rapidly and evenly in different materials, no agglomeration, fits well with various raw materials.
Powerful Functional Effects: It possesses good anti-caking, anti-settling, thickening, reinforcing and adsorbing performance, effectively improving product stability and physical strength.
Superior Stability Feature: Chemically inert, non-toxic odorless, heat-resistant and weather-resistant, insoluble in water and common solvents, keep stable performance in various production environments.
Wide Scope of Application: Multifunctional inorganic filler, widely used in food, feed, rubber, daily chemical, pesticide and coating industries with stable effect and low dosage.
Precipitated silica is amorphous silicon dioxide powder produced by precipitation method, featuring large specific surface area and strong adsorption capacity, meeting industrial and food grade standard, favored by global customers.
