White granular Precipitated Silica Felcosil-195GR form with low dust, it can be dissolved by NaOH,HF. Other kinds of acid, water and solvents cannot dissolve the product.
White powder form superfine silica. It is a wax treated, medium particle sized precipitated silica. Very low viscosity impact, high surface smoothners and sedimentation behavior.
Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
