Hydrophobic Precipitated Silica ALOS-PS-010

Hydrophobic precipitated silica ALOS-PS-010 is an organic-inorganic hybrid material produced by chemically modifying the surface of silica with a hydrophobic organic modifier. This surface functionalization significantly enhances the material's interfacial activity while maintaining the inherent structural advantages of precipitated silica. ALOS-PS-010 features high surface activity, low moisture absorption, excellent dispersibility in organic media, and outstanding compatibility with polymer systems. These properties allow it to integrate smoothly into a wide range of resin, rubber, and plastic formulations without negatively affecting processing or final product performance. In addition, ALOS-PS-010 functions as an effective rheology modifier, providing controlled thickening, thixotropy, and anti-settling behavior.
