The data represents typical values.
Special products can be developed and delivered on demand.

Specialized industries have different requirements for fumed oxides with specific properties. In order to fulfill these high technical requirements, combinations of different raw materials (SiO₂, Al₂O₃ or TiO₂), surface treatments and many manufacturing processes are employed.

The R and N grades of AEROSIL^® products listed above can be used to regulate flow tribo-charge, and stability of toner for copiers and laserprinters. AEROXIDE^® TiO₂ T 805, an efficient UV-filter, is characterized by its ease of dispersibility and low moisture adsorption.

AEROXIDE^® Alu C 805 is especially recommended for moisture sensitive powder coating applications.

Positive effects:

Regulation of toner tribo-charge
Free flow agent for toner
Improved storage stability of toner
Increased heat stability of silicone elastomers
