AEROSIL® fumed silica - more than just a powder

AEROSIL® fumed silica is an extremely versatile product. In order for you to find the AEROSIL® grade with the right characteristics for your application, we have grouped the various AEROSIL® types by raw material and method of production. Not only these, but also the behavior with water, whether hydrophilic or hydrophobic, are crucial for the final application.

You will find the AEROSIL^® grade to solve your problem in one of the following categories:

Hydrophilic fumed silica

Along with the traditional application areas (e.g. polyester, silicone, paints and coatings), hydrophilic AEROSIL^®products are used with increasing success in high technology fields.more

Hydrophobic fumed silica

Our hydrophobic products are characterized, among other things, by a low moisture adsorption, excellent dispersibility, and their ability to adjust rheological behavior, even that of polar systems.more

Fumed mixed oxides

The fumed mixed oxides are manufactured (co-fumed) using the AEROSIL^® process, and may be regarded as a mixture of SiO₂ and Al₂O₃ on the molecular level.more

Hydrophilic fumed metal oxides

The AEROSIL^® manufacturing process can also be applied to produce fumed aluminum and titanium oxides. E.g. AEROXIDE^® Alu C - a pure aluminum oxide with a hydrophilic character.more

AERODISP® - dispersions

AERODISP^® is the ideal solution for the dust-free handling of AEROSIL^® fumed silica and AEROXIDE^® fumed metal oxides.more

AEROPERL® - granulated products

In contrast to Evonik's fine-particle core product AEROSIL^®, AEROPERL^® is a mechanically stable granulate consisting of spherical particles with an average size of about 30 micrometers.more

Special products

In order to fulfill high technical requirements, combinations of different raw materials (SiO₂, Al₂O₃ or TiO₂), surface treatments and many manufacturing processes are employed. The result are our special hydrophobic silicas and metal oxides.more
