Fumed Silica, HP-150/ HP-200/ HP-380, Silicon dioxide, SiO2 Package of 10kg in a paper bag
Chemical Name
Silicon dioxide
Structural Formula
SiO2
Physical properties
Fumed silica called as well as aerosil. It is a white, amorphous，high-dispersive and minuteness powder. It dissolved caustic potash and hydrofluoric acid, but don’t dissolved water and other acids. It can form collective granule after imbibed moisture in the air. It is stable for the chemical medicine, endures high temperature, no inflammation, and insulation for electricity.
