Teflon (disambiguation)

Polymers and products commonly called Teflon

• PTFE (polytetrafluoroethylene) – the classic fluoropolymer known for very low friction, high chemical resistance and thermal stability; used for nonstick coatings, seals, and bearings.
• FEP (fluorinated ethylene propylene) – melt-processable and transparent; used where PTFE-like properties are needed in extruded films and tubing.
• PFA (perfluoroalkoxy alkane) – combines PTFE performance with melt processability and is used for corrosion-resistant components and liners.
• ETFE and related copolymers – distinct fluorinated copolymers sometimes marketed under other brand names (for example, Tefzel) used in wiring insulation, architectural films and thin, high-strength facings.
• Specialty grades – amorphous fluoropolymers (e.g., Teflon AF) and PTFE tapes or dispersions adapted for specific electrical, optical or sealing applications.

Other meanings and uses

Beyond chemistry, "Teflon" is used metaphorically — for example, to describe a person to whom criticism does not stick. The trade name also appears on consumer goods (nonstick pans, clothing treatments) and industrial coatings supplied by different manufacturers under license or as generics in some markets.

History and notable facts

The material class was discovered and developed in the 20th century and commercialized for both industrial and consumer use. The Teflon name became closely associated with PTFE and with the distinctive properties of fluoropolymers: very low surface energy, resistance to solvents and acids, and a wide useful temperature range.

Environmental and regulatory notes

Some processes and legacy chemicals associated with fluoropolymer manufacture — notably certain per- and polyfluoroalkyl substances (PFAS) used as processing aids — have raised health and environmental concerns. These issues have led to regulatory review, phase-outs of specific ancillary chemicals in some regions, and the development of alternative processing methods and higher-purity grades.
