Japan’s Shin-Etsu Silica Spherical Microparticles QSG100, QSG80, QSG30

                         

Two Silica spherical particles

Silicon dioxide spherical particles, the particle size is extremely small, the particle size distribution is narrow, and The surface is highly hydrophobized. Therefore, it is excellent in dispersibility, hydrophobicity, lubricity, and fluidity, and these properties can be imparted in the drying process by adding other powders. In addition, not only inorganic series but also organic series powders can be used.
