Hydrophilic fumed silica is a high-purity, amorphous silica material characterized by its extremely fine particle size, large surface area, and strong affinity for water. Manufactured through flame hydrolysis, it provides superior dispersion, enhanced rheological control, and improved thickening properties in various applications. This versatile silica is widely used in adhesives, coatings, sealants, personal care formulations, and pharmaceuticals, offering excellent moisture absorption, anti-caking functionality, and stability enhancement.
Product Overview
Hydrophobic Fumed Silica is a high-purity white powder with hydrophobic properties and excellent rheological behavior. It is specifically designed for controlling the rheology and thixotropy of liquid systems, adhesives, and polymers. It effectively improves powder characteristics, adjusts flowability, and prevents caking, and is widely used in coatings, inks, and other applications.
