Fujian Kerun’s annual production of 1,500 tons of high-end fluoropolymer project kicks off

Thread Content

On August 18, 2025, the groundbreaking ceremony for Fujian Kerun’s project to produce 1,500 tons of high-end fluoropolymer products per year was held. Guo Feihong, the mayor of Shaowu City, along with other relevant officials and parties involved in the project construction, attended the ceremony. Fujian Kerun Phase I (with an investment of 170 million yuan) was completed ahead of schedule, achieving domestic production across the entire industrial chain—from tetrafluoroethylene monomer to tetrafluorosulfonyl lactone, PSVE, and perfluorosulfonic acid resins. The construction of the second phase covers an area of 100 mu, with an estimated additional investment of 500 million yuan. It will involve the construction of new factories, warehouses, and facilities covering 30,000 square meters, thereby addressing the technical challenges related to high-end fluorine-containing materials such as perfluorosulfonic acid resins and stretchable ePTFE resins used in the fields of new energy, semiconductors, and aerospace. Once all the projects are completed and brought into operation, Fujian Kerun will become the world’s largest production base for perfluorosulfonic acid resins, providing the most reliable and high-quality raw materials for proton exchange membranes used in industries such as flow batteries, water electrolysis for hydrogen production, and fuel cells in China. According to sources in the fluorine chemical industry, Fujian Kerun’s project for producing 1,500 tons per year of high-end fluoropolymer products is expected to require an investment of 250 million yuan. The facility will be capable of producing 450 tons per year of perfluorosulfonic acid resin, 1,000 tons per year of polytetrafluoroethylene resin, 50 tons per year of perfluoroether rubber, as well as various intermediate compounds, precursor monomers, by-products, and other related materials.
