AEROPERL® fumed silica, titania, and alumina oxides with spherical particles serve as absorbents, carriers and fillers in a multitude of applications.
AEROPERL® is the brand name for specially granulated fumed oxides. Evonik offers AEROPERL® granulates made from fumed oxides, such as silica, titania, and alumina. The granulates are largely spherical and combine the excellent characteristics of AEROSIL® and AEROXIDE® with improved handling properties. These spherical, larger and higher aggregated particles are favorable when AEROSIL® and AEROXIDE® particles are too fine in specific applications.
AEROPERL® is mainly used as a versatile processing aid in the pharmaceutical industry. Compared to the fluffy AEROSIL® Pharma powders, AEROPERL® 300 Pharma features a greatly increased density as it consists of round shaped granules in the range of 20–60 μm. Due to its unique physico-chemical properties AEROPERL® 300 Pharma serves as glidant and as highly effective absorbent and carrier for a multitude of different applications.
