There are not many perfluoroenyl ether companies in China, and the industry has good prospects for future development.

Perfluoroalkenyl ether is a special fluorine-containing monomer and a key raw material for the synthesis of special fluoropolymers and modified fluoropolymers, including perfluoromethyl vinyl ether (PMVE) and perfluoro-n-propyl vinyl ether (PPVE). , perfluoroethyl vinyl ether (PEVE), perfluoro-2-(2-sulfuryl fluoroethoxy) propyl vinyl ether (PSVE), etc., are one of the fluorine chemical products encouraged by national policies.

According to the “Perfluoroenyl Ether Industry Market Status and Investment Prospects Forecast Report 2023-2027” released by the Industrial Research Center, from Looking at the upstream of the industrial chain, perfluoroalkylene ethers are mainly produced from hexafluoropropylene oxide as raw materials. For example, hexafluoropropylene oxide is used to prepare PSVE, PMVE, etc. At present, domestic hexafluoropropylene oxide manufacturers include Zhejiang Huanxin Fluoro Materials Co., Ltd., Sanming Haisifu Chemical Co., Ltd., Lianyungang Taizhuo New Materials Co., Ltd., etc. In addition, some perfluoroalkenyl ethers can also be produced from raw materials such as hexafluoropropylene, such as using hexafluoropropylene to prepare PPVE.

From the downstream of the industrial chain, perfluoroenyl ether can be used to produce high-purity meltable polytetrafluoroethylene, perfluoroether rubber, perfluorosulfonic acid resin, modified fluororesin, etc., which can then be used in integrated circuits, new energy, aviation, etc. Aerospace, military industry, precision equipment, chemical industry, electronic and electrical equipment and other fields. For example, perfluoro-2-(2-sulfonylfluoroethoxy)propyl vinyl ether (PSVE) can be used to produce perfluorosulfonic acid resin, which is then used to produce perfluorosulfonic acid proton exchange membranes and is further used In industries such as hydrogen and oxygen fuel cells.

From the perspective of production companies, the current domestic perfluoroenyl ether production companies are mainly Sanming Haisifu Chemical Co., Ltd. and Taixing Meilan New Materials Co., Ltd. Among them, Sanming Haisifu Chemical Co., Ltd. plans to build more than 1,300 tons of perfluoroalkylene ether; Taixing Meilan New Materials Co., Ltd. is in the trial production stage of 100 tons/year perfluoroalkylene ether. In addition, Fujian Huayi Sanai Fufuyou New Materials Co., Ltd. was approved in 2021 for 200 tons/year perfluoro-n-propyl vinyl ether (PPVE) and 80 tons/year perfluoromethyl vinyl ether (PPVE). PMVE) and 100 tons/year perfluoroethyl vinyl ether (PEVE) project, but they have not been constructed.

From the perspective of the market prospects of perfluorinated ethers, with the development of miniaturization of electronic equipment, electronic and electrical equipment fields such as automotive radar sensors, 5G communications, and AI smart terminals have increasingly higher requirements for the dielectric loss of copper-clad laminates, prompting perfluorinated ethers to The demand for flexible copper-clad laminates of alkylene ether copolymers in the electronic and electrical fields has increased, thus creating good conditions for the increase in market demand for perfluoroalkylene ethers. In addition, perfluoroalkene ether is an essential raw material for perfluoroether rubber. Perfluoroether rubber can be used to produce sealants that are resistant to high temperatures, solvents, and strong corrosive media, and are used in aerospace, petrochemical, semiconductor and other fields. The development of the industry is supported by national policies. In the future, driven by downstream industries, the domestic demand potential for perfluoroalkylene ethers will gradually be released.

Industry analysts said that the domestic perfluoroenyl ether industry has been developing for a short time, but it has made rapid progress. There are currently many companies With breakthroughs in perfluoroalkenyl ether preparation technology, in the future, driven by demand and policy promotion, new domestic companies may enter the industry and promote the increase in domestic perfluoroalkenyl ether production capacity.
