Extremely broad product range and innovative experimental products

With a number of AEROSIL® grades developed specially for the silicone industry, Evonik can offer a product range providing technical advantages and improvements for a large number of silicone systems. Moreover, we already have a broad base of novel and innovative experimental products for development of the next generation of AEROSIL® products.

These novel products will allow for continued improvement of various highly interesting properties in silicone rubber such as flowability, tear resistance, and transparency.
