The function of hydrophilic fumed silica was analyzed from the chemical point of view

Hydrophilic fumed silica was prepared by hydrolyzing chlorosilane in oxyhydrogen flame.Chemically, the loose white powder is made up of amorphous silica with high purity.Hydrophilic fumed silica can be wetted with water and dispersed in water.In addition to the traditional industrial fields, such as polyester, silicone, paint and coatings, hydrophilic vapor phase silica products are increasingly successfully applied in high-tech fields.The characteristics and high purity of gas phase silica nanoparticles make it play a leading role in the electronics and optical fiber industry.Hydrophilic fumed silica has amorphous structure by x - ray analysis.Depending on the market and application area, we can provide products with different sizes of primary particles and different specific surface areas.Some gas phase silica products can be compressed after delivery, some products are medical grade.Hydrophilic fumed silica function: suitable for processing, adjust to the best rheology;Reinforcement of silicone elastomers;Thickening of nonpolar liquids;Flow AIDS for food and industrial powders;High chemical purity;Excellent insulation performance even at high temperature;The transformation of a liquid into a powder, as in medicine or cosmetics.
