Product Overview

CE Chemicals Hydrophilic Fumed Silica 200 is a silica-based light-weight inorganic oxide powder. The manufacturing process of Hydrophobic Fumed Silica begins with the vaporization of silicon tetrachloride (SiCl₄) in an oxygen-free atmosphere. This produces a high purity of silicon dioxide. The resulting vapor is then hydrolyzed and condensed to form fumed silica. Its hydrophilic nature is the result of the presence of hydroxyl groups attached to silica atoms on the particle surface, which allows them to hydrogen bond. As a result, the substance can be dispersed in water.

Hydrophilic Fumed Silica 200 has a broad application in high-tech industries in coatings, inks, silicone rubber, adhesives, sealants, as well as cosmetics. CE Chemicals Hydrophilic Fumed Silica 200 is used in liquid system to promote the rheologic and thixotropic effect, as an thickening agent, flow-improving agent, anti-settling, anti-sagging, anti- caking agents in paints and coatings. And as a reinforcing agent in silicone rubber.

Hydrophilic Fumed Silica is available in several different grades, each with a different specific surface area (BET).
