Company Profile

    Ningxia Silane Chemical and Environmental Technology Co., Ltd. is a National High-tech Enterprise and a Gazelle Enterprise. Founded by Dr. Shen Jun in 2010, the company has a registered capital of 51.88 million RMB. Its business scope encompasses the production and sales of silicon tetrachloride, methyl silicate, and ethyl silicate; the recovery of polysilicon by-products (high boilers) and silicon tetrachloride; the recovery of polysilicon and silicone slurry; and the supply of high boiler cracking complete process packages & core equipment, along with technical services. The company is also engaged in the development of green chemical processes, new materials, and environmental protection equipment.

    Since its establishment, focusing on the green manufacturing of the polysilicon and silicone industries, the company has achieved a leading position in polysilicon slurry recovery and high boiler cracking through over ten years of R&D and engineering practice. The slurry recovery and high boiler cracking processes and core equipment developed by the company are used in over 90% of domestic polysilicon plants, including those of Daqo, GCL, TBEA, Tongwei, East Hope, Asia Silicon, Hesheng, Hongyuan, Baofeng, Runyang, and have received customer recognition. These processes enable the near 100% recovery of chlorosilane from slurry and achieve a resource utilization rate of over 95% for cracked high boilers, with a removal rate of over 95% for phosphorus and boron impurities. This strongly guarantees polysilicon quality and has realized hundreds of millions of RMB in additional benefits for polysilicon plants, along with reducing wastewater and solid waste by millions of tons. 

    The company has established close collaborations with renowned institutions and companies such as Sichuan University, Ningbo University, Hualu Engineering & Technology Co., Ltd., and Hualu New Materials in areas like new processes and new materials, achieving remarkable results. The company possesses over 12 authorized national invention patents, 2 scientific and technological achievements, 2 science and technology progress awards, 2 national industrialization projects, 2 provincial/ministerial level projects, and 2 key R&D projects. Adhering to environmental principles, the company develops new chemical technologies and products, using chemical engineering to solve environmental problems, achieving a perfect integration of chemical engineering and environmental protection, and striving forward towards a chemical industry under blue skies and white clouds.
