Our unique portfolio and global supply chain
Evonik is one of the world's leading manufacturers of synthetic amorphous silica, with production sites around the globe. We use flame hydrolysis and precipitation methods to manufacture silicium dioxide (SiO2) of a high and reliable level of quality for a broad range of industries.
Our Smart Effects business line provides a unique product portfolio of fumed and precipitated silica products under our brands AEROSIL® fumed silica, SIPERNAT® specialty silica, SPHERILEX®, ULTRASIL®, and ZEODENT®.
Besides silica, we offer various other products, including AERODISP® ready-to-use dispersions, AEROXIDE® fumed metal oxides, and functional silanes.
Reliable silica supply chain
We are close to our customers – with production sites, sales representatives, and technical support on three continents. Thanks to our outstanding silicone asset network, customers can rely on our secure, crisis-proof supply chain, with on-time delivery, product safety, and consistent quality. Keeping logistics routes as short as possible saves costs and helps reduce CO2 emissions.
With our own production facilities for chlorosilanes (STC), a precursor for silica, at our most important assets in Europe, we are independent of third-party suppliers. This puts us in a unique position in the landscape of silica producers worldwide in terms of our production and supply chain reliability.
We have consistently invested in modernizing our silica and fumed metal oxides production. We expand capacities where our customers need them, and we optimize the product mix according to market demand.
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) and more than 70 years of experience in the production of fumed metal oxides.
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.
