Fluoropolymers is a generic term used to describe various polymers containing fluorine atoms, which are classified as “specialty” polymers due to their excellent properties.

Fluoropolymers can be divided into the following macro categories:

• 1) Fluorinated polymers:
  polytetrafluoroethylene (PTFE)
  perfluoroalkyl (PFA)
  
  
• 2) Partially fluorinated polymers:
  ethylene-chlorotrifluoroethylene copolymer (ECTFE);
  ethylene-tetrafluoroethylene copolymer (ETFE);
  poly(chlorofluoroethylene) (PCTFE);
  polyvinylidene fluoride (PVDF);
  tetrafluoroethylene-hexafluoropropylene copolymer (FEP);

Due to their high fluoride content, these plastics have good chemical resistance to almost all acids, alkalis and solvents. They also have excellent non-stick and friction-reducing properties and are therefore a popular choice for coatings.
