China, the United States, and Germany are the leading exporters of Chlorotrifluoroethylene (CAS 79-38-9), collectively accounting for over 60% of global export value in 2023–2024, while South Korea, Japan, and Mexico represent the largest importers by volume and value. Imports into semiconductor-manufacturing hubs—including South Korea and Taiwan—have risen steadily since 2022, coinciding with moderate upward pressure on Chlorotrifluoroethylene prices amid tightening supply chains for high-purity fluorinated monomers.
Chlorotrifluoroethylene (CTFE) is a colorless, volatile gas at ambient temperature with a faint, chloroform-like odor; it condenses to a mobile liquid below its boiling point of −27.9 °C and freezes at −57.5 °C. It is a halogenated olefin—specifically, a fluorinated alkene—and serves primarily as a monomer in polymer synthesis. CTFE is industrially polymerized to produce poly(chlorotrifluoroethylene) (PCTFE), a high-performance fluoropolymer valued for its chemical inertness, low moisture permeability, and excellent dielectric properties. Its principal applications are in specialty polymers for aerospace, semiconductor, pharmaceutical, and cryogenic equipment components, as well as in corrosion-resistant linings and high-purity fluid-handling systems.
Intermediate, monomer for chlorotrifluoroethylene resins.
Colorless gas; faint ethereal odor. Decomposes in water.
