Silica for sustainability

Silica is part of Evonik’s Next Generation Solutions. Our silica products contribute to sustainability in several ways. They are enablers for extended product lifetime, resource efficiency, CO₂ reduction, circular solutions, and even for improved health.

Decades of silica expertise and innovation

In 1942, Evonik’s predecessor Degussa invented the flame hydrolysis pathway for fumed silica production in Germany. That's why silica is part of our DNA. We can draw on more than 80 years of expertise in the production and particle design of synthetic amorphous silica (SAS).

Today, Evonik is number one in providing innovative silica specialties and developing customized solutions, hand in hand with customers from nearly every industry. Our integrated silica/silane production platform and our quality standards ensure that we are always at the forefront of cutting-edge technology.

Application technology and handling support

Leading beyond chemistry, we also set ourselves apart from competitors with our customer service: We have local sales teams in more than one hundred countries, provide individual technical consulting in our application technology labs, and offer silica logistics and handling support. We also provide detailed life cycle assessment (LCA) data for every one of our products.
