Teflon is a registered trademark and brand name of the DuPont company for products made from three types of fluorine-containing polymers (fluoropolymers).

• Teflon-PTFE is a polytetrafluoroethylene used in GoreTex and nonstick cookware, and also as a high-frequency, high temperature dielectric/insulator for electrical wires and coaxial cables.
• Teflon-PFA is a perfluoroalkoxy used to make chemical-resistant tubing.
• Teflon-FEP is a fluorinated ethylene propylene used as a high-temperature insulation for wires, an extrudable substitute for PTFE with some compromise in performance and temperature.
• Teflon-AF is a family of statistical copolymers. They consist of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole units and are used as highly permeable membrane materials.
