Fluoropolymer
A fluoropolymer is a fluorocarbon-based polymer featuring multiple carbon–fluorine bonds. It is characterized by chemical resistance to acids, solvents, and bases. Polytetrafluoroethylene (PTFE), or Teflon® is the most commonly known fluoropolymer.
Fluoropolymer Properties
High resistance to solvents, acids, and bases
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.
Stable due to the stability multiple carbon–fluorine bonds add to a chemical compound.
Fluoropolymers may be mechanically characterized as thermosets or thermoplastics.
