Hydrophobic Precipitated Silica ALOS-PS-008

Hydrophobic precipitated silica ALOS-PS-008 is a synthetic hydrophobic silicon dioxide produced through a controlled precipitation process. It features a high degree of hydrophobicity and is surface-treated with silazane to modify the silica structure. The product appears as a fine, fluffy white powder with excellent dispersibility and moisture resistance. Owing to its advanced surface treatment, ALOS-PS-008 exhibits outstanding compatibility with non-polar and weakly polar systems, making it highly effective in improving rheology, anti-settling behavior, and flow properties in a wide range of industrial formulations.
