Siridion® is more than a brand
Siridion® means A commitment
Siridion® stands for the highest quality and satisfied customers for three reasons:
Today, Siridion® is the world’s leading chlorosilane brand for the optical fibers industry. As the partner of choice to this demanding industry, Evonik Resource Efficiency manufactures Siridion® products of unrivaled purity. Evonik operates dedicated chlorosilane manufacturing facilities at different sites to reliably deliver and to ensure our purity. Siridion® is also extensively used as key raw material for silicon-based solar cells. The higher the purity of the chlorosilanes used to manufacture solar-grade silicon, the higher the efficiency of the solar cells will be to convert sunlight into energy. This is what Siridion® offers.
Evonik Resource Efficiency has many years of experience in successfully running fence-to-fence operations with partners in Europe, North America, and Asia for various products. The strong position of Evonik as a supplier of chlorosilanes to the solar power industry is built on this strategy of joint growth with selected partners, too. The fence-to-fence cooperation model with solargrade silicon manufacturers has been tailormade for this industry and reliably delivers tangible benefits with both partners profiting from an integrated and optimized production network - known in German as "Verbund".
One of the main challenges of chlorosilanes is to ensure the highest level of purity over time. Evonik has been manufacturing Siridion® chlorosilanes for decades at the highest levels of quality and reliability. Siridion® is synonymous with "quality delivered on time". Our customers can count on us to meet their specifications and their deadlines. Every time and everywhere.
