Green Industrial Chain
Established a complete green recycling industry chain of "Silicon - Chlorosilanes - Intermediates - Functional Silanes - Fumed Silica"

The company has become the first company in the industry to complete the closed cycle of silane production chain through technical transformation. It has formed a complete industrial chain layout from silicon, the basic raw material, to intermediates such as trichlorosilane, γ1, γ2, and then to sulfur-containing silane, which realizes the effective control of product quality and cost. As for silicon tetrachloride, the by-product generated in the production process, the company will process it into fumed silica and sell it to the public; the by-product hydrogen chloride has also been recycled. Through the closed cycle of silane production chain, the company not only eliminates the need of hydrogen and chlorine purchasing, improves the efficiency of material use, but also reduces the emission of "three wastes" in the process of production, and realizes better economic and environmental benefits.
