What 三明市海斯福化工有限责任公司 does

三明市海斯福化工有限责任公司 (Sanming Hexafluo Chemicals Co., Ltd.) is a Chinese fluorine specialty chemicals manufacturer founded in 2007 and headquartered in Mingxi County, Sanming, Fujian Province. The company operates two production entities under the HEXAFLUO and HEPTAFLUO brands with a combined workforce of more than 1,270 employees, including over 200 R&D personnel, and is a national-level high-tech enterprise designated as a Specialized "Little Giant" (专精特新). It functions as a wholly-owned subsidiary of Shenzhen Capchem Technology Co., Ltd. (深圳新宙邦科技, SZSE: 300037) following the 2015 acquisition, with product and capital planning coordinated within the parent's specialty chemicals platform.

The company's core technology centers on perfluorinated compound synthesis. Its flagship product is perfluoroisobutyronitrile (C4F7N), an environmentally superior replacement for sulfur hexafluoride (SF6) in high-voltage electrical insulation, which secured China's first national regular registration for this application in 2024. Adjacent product lines include high-performance fluorinated monomers, fluorinated fine chemicals, and lithium battery electrolyte formulations, supported by a 40,000-ton electrolyte line commissioned in December 2022, a 1,000-ton C4F7N line brought online in August 2023, and a 15,000-ton high-performance fluorine materials line via the Heptafluo subsidiary. Hexafluo's C4F7N has been qualified for 550kV SF6-free gas-insulated switchgear (GIS), including the world's first such deployment at State Grid Wuhan.

The business model is B2B industrial chemicals sales under volume- and specification-based contracts. The principal customers are power grid OEMs and utilities (Hitachi Energy for global SF6-free GIS, State Grid Corporation of China domestically) and lithium-ion battery manufacturers served through the Capchem parent's electrolyte channel. Reported revenue milestones were RMB 1 billion (2016), RMB 1.5 billion (2021), and RMB 2 billion (2022), with H1 2023 output value of RMB 1.2 billion (+20% YoY). 2022 R&D spend was RMB 84.26 million, supporting a multi-product fluorination technology platform.
