Silica matting agent AH-500
Product Description
1, silica, molecular formula: SiO2 • nH2O; Appearance: white granular or powder;
2, the nature of the product silica Bulk density 0.192-0.320, melting point 1750οC, porosity, internal large surface area, the raw rubber in the greater dispersion of power, with mixing fast, high strength. Chemical properties: silica is classified as inert material, has a high insulation, insoluble in water and acids and solvents, but soluble in caustic soda, and hydrofluoric acid, the high temperature without decomposition
.
