Polychlorotrifluoroethylene (PCTFE) is irreplaceable and there is a high demand for film-grade PCTFE applications.

Polychlorotrifluoroethylene (PCTFE) is synthesized from the homopolymerization of chlorotrifluoroethylene. It is a type of thermoplastic with high hardness, creep resistance, low gas permeability, and excellent radiation resistance. , currently mainly used as anti-corrosion linings for chemical storage tanks, pumps, valves and other products, as well as for the production of experimental vessels, electronic seals, radiation protection products, etc., and are widely used in national defense, electronic information, chemical industry, pharmaceuticals, and machinery manufacturing. and other fields.

According to the“China Polychlorotrifluoroethylene (PCTFE) Industry Application Market Demand and Development Opportunities Research Report 2022-2027” released by the Industrial Research Center shows that PCTFE started earlier and has excellent product performance, and is still widely used today. After years of development, the market demand for PCTFE has shown a steady growth trend. Globally, the PCTFE market size was approximately US$1.4 billion in 2017 and will grow to US$1.6 billion by 2020. Pumps, valves, etc., as common general machinery, have high market demand. In the first half of 2020, my country’s pump production was 76.9 million units and valve production was 2.55 million tons. Benefiting from the development of terminals, PCTFE has room for development in the domestic market.

At present, PCTFE can be divided into film grade, lubricant grade and product grade. Among them, film grade PCTFE has higher application demand and accounts for about 74% of the market. It is mainly used in electronic and electrical, pharmaceutical and other fields; product grade PCTFE accounts for 26%. It is used for the anti-corrosion, packaging and sealing of electronic devices, precision electronic devices, liquid nitrogen storage tanks and other products; lubricating oil grade PCTFE is a special customized product, mainly used in the nuclear industry and aerospace fields.

Lubricant grade PCTFE is also known as fluorochlorine oil. The product has high chemical stability and excellent lubrication performance. It is mainly used in high temperature and corrosive environments. At present, fluorofluorocarbon oils that have been commercialized on a large scale include a series of products produced by companies such as Daikin of Japan and Hooker of the United States. Great Wall Lubricants of my country has also successfully developed related products.

Product-grade PCTFE is the original corrosion-resistant material in the atomic energy industry. It has high chemical stability and corrosion resistance, and has high application demand in the semiconductor field. At present, the product-level PCTFE company that has achieved mass production is Daikin Company of Japan. The company has four brands of products that can meet the needs of different scenarios. my country’s Changshu Xinhua Chemical and Qingdao Hongfeng Fluorosilicone Technology Co., Ltd. have also achieved product-level PCTFE production.

Thin film grade PCTFE is a polymer material with high thermal stability, low dielectric constant and low hygroscopicity. It is an excellent packaging material. Currently, companies that have achieved large-scale production of thin-film-grade PCTFE include Daikin Corporation of Japan and Honeywell Corporation of the United States. The products produced by the two companies have different application fields. The products produced by Daikin Corporation of Japan are mainly used in solar collectors and displays; Honeywell makes products that are used to package and seal bottles of pharmaceuticals, chemicals, and personal care products. my country’s Qingdao Hongfeng Fluorosilicone Technology Co., Ltd. has also realized the production of thin-film grade PCTFE.

Industry analysts said that PCTFE has excellent performance and is irreplaceable in some fields. It has high added value and good application prospects. . PCTFE can be mainly divided into three types. Among them, film-grade PCTFE has high application demand, while lubricating oil-grade PCTFE is a high-end product. Currently, some domestic companies have achieved PCTFE production, but foreign companies still monopolize the market in the high-end field.
