FEP – Fluorinated Ethylene Propylene Applications

Fluorinated Ethylene Propylene (abbreviated FEP) was originally invented by DuPont, and sold under their PTFE brandname. It is a thermoplastic resin that can be melt processed using conventional techniques. FEP films are available with one or both sides treated for bonding. FEP typically melts between 535 – 550 Degrees F

Benefits & Liabilities of FEP


  • Wide thermal operating range from -190C to 205C
  • Excellent chemical resistance
  • Excellent Corrosion Resistance
  • Low coefficient of friction
  • Excellent resistance to UV and X-ray radiation
  • Highly Transparent
  • Excellent electrical insulating properties
  • Dimensional stability
  • Non-Stick
  • Low co-efficient of friction
  • Flame Retardant
