HIFULL Hydrophobic Fumed Silica
Hydrophobic fumed silica is a form of silicon dioxide (commonly known as silica) that has hydrophobic groups chemically bonded to the surface. It’s treated silica or structure-modified silica. HIFULL hydrophobic fumed silica is structure modified silica after being treated by HMDS, PDMS, DDS.

For systems requiring hydrophobic grades, HIFULL treated fumed silica deliver a number of performance benefits including:
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.
Commercial available fumed silica can be divided into two groups: hydrophilic fumed silica and hydrophobic fumed silica. Because of the above-mentioned features, it is widely used as an important ingredient in many industries such as silicone rubber, paint, and plastics industries.
