They are used to for rheology control (thickening, anti-sag, anti-setting, thixotropy), reinforcing (improve strength). SiSiB produces both hydrophobic and hydrophilic fumed silica.

Hydrophilic fumed silica is manufactured by hydrolysing volatile chlorosilanes in an oxyhydrogen flame. In chemical terms, the loose white silicone powder consists of highly pure amorphous silicon dioxide. Hydrophilic silica is wetted by water and can be dispersed in water.

Hydrophobic fumed silica produced by the chemical reaction of hydrophilic silica with reactive silanes or silicone fluids, like chlorosilanes, hexamethyldisilazane and polydimethysiloxane. The treated fumed silica powder has water-repellent properties and is no longer dispersible in water.
