Features
Fumed silica (fumed white carbon black) is one of the most important high-tech ultrafine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other aspects of its specific properties. It has unique characteristics in many disciplines and fields and plays an irreplaceable role.
