A fluoropolymer is a fluorocarbon based polymer with multiple strong carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases.

History

Fluoropolymers were accidentally discovered in 1938 by Dr. Roy J. Plunkett when he was polymerizing tetrafluoroethylene to form polytetrafluoroethylene (PTFE or more commonly known by the DuPont trademark Teflon^[1]).

Properties

Fluoropolymers share the properties of fluorocarbons in that they are not as susceptible to the van der Waals force as hydrocarbons. This contributes to their non-stick and friction reducing properties. Also, they are stable due to the stability multiple carbon–fluorine bonds add to a chemical compound. Fluoropolymers may be mechanically characterized as thermosets or thermoplastics. Fluoropolymers can be homopolymers or copolymers.^{[citation needed]}

Applications

They are often applied to manufactured metal parts by electrostatic powder coating, or attached in large sheets with epoxy to line the interior of large metal and non-metal containers.^{[citation needed]}

Examples of monomers used to prepare fluoropolymers

• Ethylene (E)
• Propylene (P)
• Vinyl fluoride (VF1)
• Vinylidene fluoride (VDF or VF2)
• Tetrafluoroethylene (TFE)
• Hexafluoropropylene (HFP)
• Perfluoropropylvinylether (PPVE)
• Perfluoromethylvinylether (PMVE)
• Chlorotrifluoroethylene (CTFE)
