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 (or 30 millionths of a meter). The highly porous granules of pure silicon dioxide are eminently suitable as carrier substances for active ingredients, fragrances, and flavors in liquid or paste form, or for other liquids that must be incorporated into powder formulations. AEROPERL® facilitates these kinds of manufacturing processes because its granular property makes it remarkably easy to handle.
Positive effects:
  • Dust free and easy handling
  • High purity
  • Excellent flow both loaded and unloaded
  • High adsorption capacity, fast uptake
  • Low thickening of solvents
  • Easy separations from liquids and gases
