FEP (copolymer of tetrafluoroethylene and hexafluoropropylene) has excellent chemical inertness, exceptional electrical properties, heat, atmospheric and radiation process resistance and can be sterilized. The strength of FEP is its high impact resistance, while stiffness and temperature resistance are lower than those of PTFE. However, stiffness and wear properties can be significantly increased with the addition of fillers.
FEP is typically applied in the telecommunication, construction, semiconductor, paper, chemical, textile, food processing and packaging industry.
It is mainly used for the production of transparent wires and cables, films, linings and tapes. FEP can be used as non-stick material in the compression moulding processes or as melting material between fluorinated resins.
Available as unreinforced, reinforced and masterbatches, Flontech can supply both virgin and reprocessed FEP based products, as well as special tailormade compounds.
Some of the most used FEP compounds contain glass fibers and pigments.
FEP properties include:
- Wide range of operating temperatures (from -70°C up to +260°C).
- High chemical resistance.
- Extremely smooth surface of the extruded bodies.
- Excellent transparency.
- High dielectric strength.
- Stability and resistance to UV rays.
- Anti-adhesion and non-flammability properties.
