Our hydrophobic SiO2 nano powder is processed by organic hybridization and the production method is vapor phase.

Unlike the original hydrophilic silica, the hydrophobic fumed silica cannot be wetted by water. Although the density of hydrophobic fumed silica is greater than that of water, they can float on water. By surface treatment of fumed silica, its technical performance can be optimized in some specific application fields, which can effectively improve the rheological properties of many liquid polymer systems, especially in epoxy resin systems.

Fumed silica is one of the extremely important high-tech ultrafine inorganic new materials. Because of its small particle size, it has a large specific surface area, strong surface adsorption, high chemical purity, good dispersion, thermal resistance, electrical resistance, etc. The special performance, with its superior stability, reinforcement, thickening and thixotropy, has unique characteristics in many disciplines and fields, and has an irreplaceable role. Widely used in various industries as additives, catalyst carriers, petrochemicals, rubber reinforcing agents, plastic fillers, ink thickeners, soft metal polishing agents, insulating and heat insulating fillers, fillers for high-level daily cosmetics and spray materials, etc. .
