Hydrophilic fumed silica is produced by the hydrolysis of volatile chlorosilanes in a hydrogen-oxygen flame. From a chemical point of view, these loose white powders are composed of high-purity amorphous white carbon black. Hydrophilic silica is wettable with water and dispersible in water. In addition to traditional industrial applications such as polyesters, silicones, paints and coatings, hydrophilic fumed silica products are increasingly used in high-tech fields. The nanoparticle characteristics and high purity of fumed silica have led its application in the electronics and optical fiber industries. X-ray analysis of the hydrophilic fumed silica has an amorphous structure. Depending on the market and application area, we can provide products with different primary particle sizes and specific surface areas. Some fumed silica products can be supplied compressed, and some products are pharmaceutical grade.

Functions of hydrophilic fumed silica: suitable for processing and adjustment to the best rheology; reinforcement of silicone elastomers; thickening of non-polar liquids; flow aids for food and industrial powders; Purity; excellent insulation properties even at high temperatures; liquids are transformed into powders, such as medicine and cosmetics.
