FEP films
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 used in all industrial applications due to its outstanding chemical and thermal resistance (up to 200°C). It can be used as an anti-adhesive 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 protection
- extremely smooth surface
- good release effect
- very good punchability
- good weldability
Compared in detail to PTFE, it also exhibits excellent chemical resistance and electrical properties (up to very high frequencies), as well as good weather resistance. It has better radiation resistance and much higher impact strength, but lower maximum application and dimensional stability under heat, and it is also not as rigid and strong. Although not quite crystal clear, it is transparent (essentially from 250/300 to 7000 nm) and colorless with a bluish tinge.
Main applications for FEP film
FEP film is used as a die-cut part and tape in many industrial sectors: medical technology, telecommunications, wire & cable, semiconductors, paper industry, chemicals, textiles, food processing, packaging, composites, protective coatings.
