Years of expertise in solutions



Silicone rubber is used in the most varied industries, and is becoming increasingly important particularly in the automotive and textile industries.The development of special hydrophobic AEROSIL® grades has allowed production of modern adhesives and sealants that are helping shape the technologies of the future in automotive production. With these modern silicone sealants, it is possible to use structural glazing for light-transparent roof and facade structures. silicone-coated fabrics, in contrast, are used not only in technical fields, such as textile structural applications, but also find interesting application in other products. In silicone-coated textiles such as baby socks, for example, silicone rubber is used that, thanks to the AEROSIL® reinforcing component, provide a coating of high mechanical strength with anti-slip properties. Coatings of this type also repel dirt and water.




Extremely wide product range, novel and innovative experimental products




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




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