Teflon® AF is a family of amorphous fluoropolymers. These materials are similar to other amorphous polymers in optical clarity and mechanical properties, including strength. They also resemble fluoropolymers in their performance over a wide range of temperatures, outstanding electrical properties, and chemical resistance. They are distinct from other fluoropolymers in that they are soluble in selected solvents and have high gas permeability, high compressability, high creep resistance, and low thermal conductivity. They have the lowest dielectric constant of any known fluoropolymer.
