AEROSIL®
Fumed Silica - Hydrophilic and Hydrophobic
For over 70 years Evonik’s™ AEROSIL® has been a market leading brand of fumed silica. With a unique range of both hydrophilic and hydrophobic grades available the number of applications are endless. Fumed (pyrogenic) silica is composed of synthetic silicon dioxide (SiO2) which is entirely amorphous, eliminating the risks posed by crystalline silica.
One of the main applications for fumed silica is increasing the viscosity, pseudoplasticity and thixotropy of a wide range of liquid systems. However there are many more applications besides this common use case. Evonik’s™ AEROSIL® range is the most extensive range of fumed silica on the market, with many of their products tailored for particular applications. The versatility of AEROSIL® means that it can be found all around us, from the paints on our walls to the fertilizers on our crops. Read on to find out more about this exciting product range.
