Ethylene-chlorotrifluoroethylene copolymer (ECTFE) has a low degree of industrialization and large room for future market development.

Ethylene-chlorotrifluoroethylene copolymer (ECTFE) is a fluoropolymer formed by alternating copolymerization of ethylene and chlorotrifluoroethylene at a molar ratio of approximately 1:1. It has excellent acid and alkali resistance, solvent resistance, corrosion resistance, penetration resistance, It has high temperature resistance and outstanding processability, as well as extremely low permeability and excellent electrical properties. It can be widely used in many fields such as construction industry, petrochemical industry, automobile, aviation, chemical engineering, optics and microelectronics industry. .

At present, the preparation methods of ethylene-chlorotrifluoroethylene copolymer (ECTFE) mainly include suspension polymerization, emulsion copolymerization, solution polymerization and microemulsion polymerization. Among them, the emulsion copolymerization method is the most commonly used production method. Its advantages are that it uses water as the reaction medium, has good heat dissipation, low cost, and is environmentally friendly. The disadvantage is that some emulsifiers and other additives are left in the product, and the purity is not high.

From the perspective of manufacturing companies, according to the“In-depth Market Research and Investment Strategy of the Ethylene-chlorotrifluoroethylene Copolymer (ECTFE) Industry from 2022 to 2026” released by the Industrial Research Center The Recommendation Report shows that at this stage, only one company in the world, Solvay, is producing ethylene-chlorotrifluoroethylene copolymer (ECTFE). Domestic Dalian Zhenbang Fluorine Coatings Co., Ltd. has an ECTFE pilot plant in preparation. There are reports, but there is no large-scale production of ECTFE. In addition, Sinochem Blue Sky has built a 100-ton/year ethylene-chlorotrifluoroethylene copolymer (ECTFE) production unit.

Judging from the patent layout related to ethylene-chlorotrifluoroethylene copolymer (ECTFE), the United States is in a leading position in the research and development field of ethylene-chlorotrifluoroethylene copolymer (ECTFE) and is the world’s largest source of technology, with a number of patent applications reaching More than 400 pieces. In addition to the United States, China has more than 400 ethylene-chlorotrifluoroethylene copolymer (ECTFE) patents, ranking second; Japan has more than 300 ethylene-chlorotrifluoroethylene copolymer (ECTFE) patents, ranking third. .

Judging from the patent applicants for ethylene-chlorotrifluoroethylene copolymer (ECTFE), foreign companies such as Daikin, DuPont, Asahi Glass, Osment, Saint-Gobain, LG Chem, 3M, Solvay, Mitsubishi, etc. have patent applications in ethylene-chlorotrifluoroethylene. It has strong R&D capabilities in the field of copolymers (ECTFE) and has applied for a large number of patents related to ethylene-chlorotrifluoroethylene copolymer (ECTFE). In China, the main ones are Zhejiang Research Institute of Chemical Industry, Sinochem Blue Sky, Changzhou Zhongying Technology, Zhonghao Chenguang Chemical Industry Research Institute, Beijing University of Chemical Technology, etc.

Industrial analysts said that ethylene-chlorotrifluoroethylene copolymer (ECTFE) has excellent comprehensive properties and can be used in cutting-edge low-temperature technologies. Sealing, anti-corrosion coatings for photovoltaic and wind power generation, high moisture-proof films for pharmaceutical packaging, flame retardant films for advanced cables, etc. At present, the ethylene-chlorotrifluoroethylene copolymer (ECTFE) industry is still in the initial stage of development, and there is great room for expansion in the industrialization and large-scale application of ethylene-chlorotrifluoroethylene copolymer (ECTFE).
