Good Price Carbon Black Powder Precipitated Silica For Thickening Toothpaste
Precipitated silica, commonly known as white carbon black, also known as hydrated silicic acid, light silica, chemical expression is generally written as mSiO2 • nH2O, the appearance of white highly dispersed amorphous powder, also processed into pellets as a commodity. The specific gravity is 2.319 to 2.653, and the melting point is 1750 °C. Insoluble in water and most of the acid, it will become aggregated fine particles after absorbing water in the air. It is stable to other chemicals, does not decompose under high temperature, and does not burn. It has high electrical insulation and porosity. Large internal surface area, large dispersion in raw rubber
