Used as a key building block in the synthesis of high-performance polymers, particularly fluorinated polyetherketones and polyimides, which exhibit exceptional thermal stability, chemical resistance, and low dielectric constants. These materials are suitable for aerospace, microelectronics, and semiconductor applications where durability under extreme conditions is required. Also employed in the development of specialty coatings and membranes with non-stick, anti-corrosive, and water-repellent properties. Its fluorinated structure enhances oxidative stability, making it valuable in advanced material science and electrochemical devices.
