Evonik silica for silicone rubber
With silica, you can precisely control the product performance of your silicone rubber, such as RTV-1C, RTV-2C, HCR and LSR.
Our way of tear-testing: Teamwork!
When it comes to silicone rubber solutions, tear-testing is just the beginning. From reinforcement and thickening to visual properties, our innovative silica products and concepts system¬atically improve the quality and functionality of your product. Count on us to work in close cooperation with your team and develop solutions tailored to your needs. The silica specialists at Evonik — Inside, to get it right.
The silica products of Evonik enable the optimal adjustment and improvement of rheological, mechanical, and optical properties. In addition, special types of AEROSIL® fumed silica and AEROXIDE® fumed oxides allow for creating ultra-transparent or particularly heat-resistant systems. Our SIPERNAT® product range also offers the option of using precipitated silica. The adhesion promoters and crosslinkers of our Dynasylan® grades complete our product portfolio for silicone rubber.
