Hydrophilic Precipitated Silica
Product Introduction
Precipitated silica is further divided into traditional precipitated silica and special precipitated silica. The former refers to silica produced with sulfuric acid, hydrochloric acid, CO2 and water glass as the basic raw materials, while the latter refers to silica produced by special methods such as supergravity technology, sol-gel method, chemical crystal method, secondary crystallization method or reversed-phase micelle microemulsion method.
