FEP

Fluorinated thermoplastic material with excellent thermal, electrical and chemical inertness properties. Widely used for different industrial applications for its excellent chemical resistance up to 200° C.
The most common format being, skived ﬁlm, it can be used as non-stick material in the compression moulding processes, or melting material between fluorinated resins.
