SIRIDION® silanes are the backbone of the silane production network. They offer maximum purity for demanding industries.
SIRIDION® is the Evonik brand name for high-purity chlorosilanes, essential raw materials primarily used in the production of semiconductors and glass fibres. These play a key role in the development of modern communication technologies. The high purity and consistent quality of SIRIDION® chlorosilanes are crucial for these industries' precise and demanding processes. Evonik has extensive expertise in the production and handling of SIRIDION® chlorosilanes.
Chlorosilanes including silicon tetrachloride (STC) and hexachlorodisilane (HCDS) are produced by carefully directed synthesis from metallurgical silicon, so they are not by-products of other processes. During production, they are purified in several steps. In the end, they have purities of up to 99.9999 percent, guaranteed by strict quality controls.
SIRIDION® chlorosilanes form the basis for a broad portfolio of functional silanes being the backbone of Evonik's entire silane production network. This also includes brands such as DYNASYLAN® and PROTECTOSIL®, as well as silica from the AEROSIL® brand. There are three production sites for SIRIDION® chlorosilanes in Europe.
Due to their chemical properties, chlorosilanes must be handled with care. Especially for SIRIDION® Evonik utilizes various returnable containers with valves to ensure safe storage and transportation. A dedicated SIRIDION® Incident Response Team provides round-the-clock assistance in the event of a hazard. Customers can rely on Evonik to take care of the safety and efficiency of their production.
