Compatibility consideration (PTFE hose)

Three factors give PTFE its unique properties with regard to wide ranging fluid compatibility and resistance to corrosion:

  • A strong interatomic bond between the fluorine and carbon atoms, making it very difficult for other atoms to bond with it
  • The structure of the molecule itself. Carbon atoms form the backbone of the molecule and are completely shielded by the fluorine atoms surrounding them
  • The molecules form long polymer chains which result in a higher molecular weight than most polymers, giving stability to the material
