FNG Water Resistant Silica Gel (Non-Cracking Silica Gel)
Description
FNG water-resistant silica gel is a white or off-white multi-microporous particle. Main component SiO2·nH2O. Insoluble in water and inorganic acids; soluble in hydrofluoric acid and concentrated caustic soda solutions. High mechanical strength. It is a heterogeneous shaped silica gel made from general silica gel through further processing: it keeps the pore structure and adsorption properties of ordinary homogeneous silica gel while also offering good water resistance — it does not crack in water — thus expanding the application range of silica gel.
