Used primarily as a surfactant and intermediate in the production of fluoropolymers and fluorinated materials. It is applied in the manufacturing of coatings, adhesives, and sealants to enhance water and oil repellency. Also employed in the electronics industry for its dielectric properties in the production of semiconductors and other electronic components. Additionally, it serves as a key ingredient in the formulation of firefighting foams due to its ability to suppress flammable liquid fires effectively. Its chemical stability and resistance to degradation make it suitable for use in harsh environments.
