In fluorine chemical, Yuji Tech has been dedicated to R&D of production of ODS alternatives, fluoropolymers and fluorinated fine chemicals for years, and has become an international leading innovation enterprise in fluorine chemical research and production. Yuji Tech has undertaken the projects of Development and Industrialization of ODS Alternatives from Ministry of Environmental Protection and Development and Industrialization of ODS Alternatives from the Industry and Information Technology Department of Shaanxi Province. In 2014, the project Development and Application of the Manufacturing and Catalytic Technology of Zero ODP and Environmentally Friendly Fluorides by Yuji Tech won the second prize of Beijing Science and Technology Award. In 2016, Yuji Tech won the first prize of "Shaanxi Provincial Science and Technology Award". In 2017, Yuji Tech won the second prize of “State Science and Technology Invention Award”. At present, Yuji Tech has applied for 62 invention patents, of which 20 have been granted. Yuji Tech's main fluorine chemicals cover refrigerants, blowing agents, aerosol propellants, fire extinguishing agents, cleaning agents, electronic gases, Insulating gases, isocyanates, perfluoroalky iodides, fluorinated intermediates, fluoropolymers, etc.

HFO-1336mzz(Z)

HFO-1336mzz(Z); HFO-1336mzz; Hexafluoro-2-butene; cis-1,1,1,4,4,4-Hexafluoro-2-Butene

As a fourth-generation foaming agent with a low GWP value, HFO-1336mzz can replace HFC-245fa and HFC-365mfc in the field of rigid polyurethane foams. It is a preferred product due to its zero ODP, low GWP, non-flammability, high efficiency and thermal stability.
