HIFULL Hydrophilic Fumed Silica
Hydrophilic fumed silica is a silica-based polymer with a tendency of absorbing moisture. It is used in high-technology fields or as an ingredient in paints, coatings, electronics, and optical fibers industries.
There are various grades of hydrophilic fumed silica, which are defined by their amorphous structure. It is used to provide thixotropic properties in coatings and adhesives. It also assists in enhancing flow in the production industry, such as cosmetics and pharmaceuticals.
HYDROPHILIC FUMED SILICA
For the total 6 grades of HIFULL hydrophilic fumed silica, the main difference lays in the specific surface area, which affects its functions, such as thickening performance, thixotropic properties.

Performance benefit
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.
