Let’s give a thumbs up and encouragement to the achievements made in China’s chemical technology and equipment sector. Your participation in the discussion serves as the greatest motivation! ********************** [Ten Years of Great Development in Chemical Equipment] This is a continuously updated summary thread; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On March 28, 2025, good news came from Jiangxi Lihua Chemical Co., Ltd. After nearly three years of research and development efforts, the company’s technical personnel successfully developed a new fluoropolymer—PCTFE resin—through independent innovation. Qualified products have also been produced, marking a breakthrough for China in the field of polychlorotrifluoroethylene resin production. It is stated that PCTFE resin (the full name being polytrifluorochloroethylene) is a polymer with a linear main chain composed of repeating units, formed through polymerization initiated by trifluorochloroethylene radicals; it is also a thermoplastic fluoropolymer. PCTFE resin is a crystalline polymer with a melting point of 213±3°C and a density of 2.13 g/cm3. It possesses excellent properties such as resistance to low temperatures, high pressures, and radiation, as well as good gas barrier properties and high mechanical strength. PCTFE material maintains its physical properties and chemical stability over a wide temperature range from extremely low temperatures of -240°C to high temperatures of 150°C, and it also possesses excellent processability. The water vapor permeability of the film products it manufactures is the lowest among all transparent plastic films, demonstrating excellent barrier properties. PCTFE resin is widely used in low-temperature cryogenic applications (liquid hydrocarbons, low-temperature liquefied gases) for sealing, valves, compressors, pumps, as well as in food and pharmaceutical packaging. Furthermore, taking advantage of its radiation resistance, PCTFE can be used to manufacture soft seat materials and radiation-resistant components for nuclear reactors ； Thanks to its inertness, it can be used to manufacture catheters for certain medical devices. Innovation is not a slogan, but the product of action and creation. During the development of PCTFE resin, Jiangxi Lihua Chemical Industry also faced numerous difficulties and challenges. Yang Zuoning, the company’s general manager, has personally presided over numerous R&D meetings, coordinated the resolution of technical challenges, stimulated the innovative thinking of R&D staff, and defined the R&D directions for various stages. With the strong support of the board of directors and the careful planning of the general manager, the company’s R&D team worked together to overcome one technical challenge after another, conducting thousands of experiments, and ultimately succeeded in developing a PCTFE resin with excellent performance. “A truly good product needs to be recommended by others, not promoted by itself. Currently, the PCTFE resin produced by Jiangxi Lihua Chemical has been certified for use by customers and has gained market acceptance. The trust and recognition from customers are important driving forces for a company’s innovation capabilities, and they serve as the best proof of a product’s value. Yang Zuoning, general manager of Jiangxi Lihua Culture and Industry, said that in the future the company will continue to adhere to the innovation-driven development strategy, striving to provide customers with higher-quality and more diverse products and services. The company will leverage technological innovation to enhance product performance, meet customer needs through high-quality services, and contribute its wisdom and efforts to the healthy development of the fluoropolymer industry, helping it reach new heights.
