Fumed silica, or pyrogenic silicon dioxide, is one kind of pure amorphous white inorganic powder that has a high specific surface area, nano-scale primary particle size, and a relatively high (among silica products) concentration of surface silanol groups. The properties of fumed silica can be chemically modified by reaction with these silanol groups.
Synonyms: Pyrogenic silica, Fumed Silica Dispersion, Silicon Dioxide, Fumed SiO2
Chemical Formula: SiO2
CAS Number: 112945-52-5

When fumed silica is used as filler or additives, it helps in thickening, reinforcement, transparency, free-flow, thixotropic performance, dielectric properties, anti-settling, heat insulation, and anti-sagging. For example, for powder products, HIFULL fumed silica is used as an anti-caking agent; for liquid products, HIFULL fumed silica is used as an anti-settling agent or suspending agent.
