White powder precipitated silica by selection of raw materials, with low iron raw materials. It can be dissolved by NaOH, HF. Other kinds of acid, water and organic solvents cannot dissolve the product. Resistance to high temperature, no combustion, good insulation, odourless properties.
In the silicone rubber industry, Precipitated Silica not only has better tensile strength and wear resistance, but also has good transparency, no whitening and no deformation when stretched.
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.
White granular form, Precipitated Silica White Granular Silica can be dissolved by NaOH,HF. Other kinds of acid, water and solvents can not dissolve the product.
