Polyfluorocarbon refers to a class of fluorinated polymers that contain carbon-fluorine bonds. These materials are known for their chemical resistance, thermal stability, and low surface energy, making them useful in various applications, including coatings, seals, and insulators. Polyfluorocarbons are also notable for their environmental impact, as some can persist in the environment and contribute to pollution. They are often studied for their potential health effects and environmental persistence.
