FEP – FILM

FEP film is a fluorinated thermoplastic material (a polymer of tetrafluoroethylene and hexafluoropropylene). It offers excellent thermal, electrical and chemical inertness properties. FEP is widely used in all industrial applications due to its excellent chemical and thermal resistance (up to 200 °C). It can be used as a non-stick material in compression molding processes (vacuum applications) or as a melting material between fluorinated resins.

8 main advantages of FEP films

  • operating temperatures above 200°C
  • excellent resistance to solvents and chemicals
  • excellent electrical properties
  • flame resistance
  • extremely smooth surface
  • good release properties
  • very good punchability
  • good weldability

In a detailed comparison with PTFE, it has similar excellent chemical resistance and electrical properties (up to a very high frequency) and good weather resistance. It has better radiation resistance, much higher impact strength but lower peak application and dimensional stability in heat, and it is also not as rigid and strong. Although it is not completely crystal clear, it is transparent (essentially from 250/300 to 7000nm) and colorless with a bluish tint.

Main applications of FEP film

FEP film is used as die-cutting and tape in many industrial fields: Medical, telecommunication, wire & cable, semiconductor, paper industry, chemicals, textiles, food processing, packaging, composites, protective coating.
