Precipitated silica 165, 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.
Silica 175GR is white granular rolled by German roll squeezer machine, with low dust, high bulk specific weight, un-floating, and easy to be transported and processed.
140 Powder White Powder form, it can be dissolved by NaOH, HF. Other kinds of acid, water and solvents cannot dissolve the product. Resistance to high temperature, no combustion, good insulation, odourless properties
