endless screw with Xylan fluoropolymer for meat sector


A fluoropolymer is a fluorocarbon-based polymer with multiple carbon and fluorine bonds. It is characterised by a high resistance to solvents, acids, and bases. Fluoropolymers share the non-stick and low-friction properties of fluorocarbons. Thanks to the multiple carbon and fluorine bonds, they are mechanically characterized as thermoset or thermoplastic. They can be homopolymers (macromolecules formed by identical monomers) or copolymers (macromolecules formed by two or more different monomers).

Fluoropolymer properties

  • Low surface energy
  • Low coefficient of friction
  • High resistance to chemical agents
  • High abrasion resistance
  • Stable over a wide temperature range: from -270 °C to 300 °C
  • Low electrical conductivity

Examples of fluoropolymers

  • PVDF: it is a polyvinylidene fluoride, like Kynar or Hylar
  • PTFE: it is a polytetrafluoroethylene, the best known is Teflon
  • PCTFE: it is a polychlorotrifluoroethylene, like Neoflon
  • FEP: it is a fluorinated ethylene-propylene, like Teflon FEP
  • PFA, MFA: it is a perfluoroalkoxy polymer, like Hyflon
