Along with the traditional polyester, silicone, paints and coatings applications, hydrophilic AEROSIL® products are used with increasing success in high technology fields. The particle nature and high purity of fumed silica play key roles in the electronics and optical fibers industries.
Furthermore, the hydrophilic AEROSIL® grades are characterized by an X-ray amorphous structure. Depending on the market and application, products with various primary particle sizes and different BET-surface areas are available. Certain types are also available in compacted form (V and VV grades) and in a pharmaceutical grade.
