SILICA FROM EVONIK TRANSFORM LIQUIDS INTO POWDERS.
Low-dust powders with good flow capabilities are easier to dose and process than viscous or sticky liquids, especially when the product is mixed with other powders or granulates. SIPERNAT® specialty silica and AEROPERL® products display a high absorption capacity, good flow capability, and chemical purity. Depending on the application, products with different particle sizes are available – as well as low-dust options. Evonik also offers special products for industries with high regulatory requirements, such as the pharmaceutical industry.
Carrier silica from Evonik have a porous, sponge-like structure. These pores absorb liquid, without changing the shape of the silica particles. A dust-free microgranular absorbate can be created using a dust-free microgranular silica like SIPERNAT® specialty silica.
Using SIPERNAT® specialty silica or AEROPERL® silica as carriers is very simple. First, the silica is placed in a suitable powder mixer, such as a paddle mixer, plowshare mixer or belt mixer. With the mixer running, the liquid is then added as a fine dispersion. Long and intensive mixing should be avoided in order to retain the porous structure of the silica.
