Everflon™ FEP (fluorinated ethylene propylene) is a melt processable fluoroplastic. Everflon™ FEP can be used in applications that don't require the enhanced properties, and temperature rating of Everflon™ PFA.
Everflon™ FEP fluoroplastics are processed by conventional melt extrusion techniques and by injection, compression, transfer and blow molding processes. Everflon™ FEP fluoroplastics are ideal for wire coating and molding a wide variety of end use articles and components.
Everflon™ FEP offers an excellent combination of properties characteristic of all fluoroplastics; a wide service temperature range, exceptional dielectric and electrical properties, low coefficient of friction, low flammability and chemical resistance. Everflon™ FEP has a service temperature range, up to 200°C (392°F).
While Everflon™ FEP can be fabricated into solid shapes and molded articles it is best known as an industry leading product line in the wire and cable industry where it is used for wire coating and cable jacket fabrication. Everflon™ FEP offers wire and cable OEMs a high performance fluoroplastic material with excellent electrical properties, ease of processing and consistent performance.
The Everflon™ FEP product line is one the broadest in the industry. With Melt Flow Rates (MFR) from 3 to 30, and a wide range of application specific grades, Everflon™ FEP is uniquely positioned to offer exceptional performance in both general purpose and high speed wire and cable constructions.
Why is Everflon™ FEP. |
||
| Chemical Compatibility | Electrical Reliability | Wide Thermal Range |
|---|---|---|
|
Everflon™ PFA is chemically inert and solvent-resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds, such as chlorine trifluoride at elevated temperatures and pressures.
It also has low permeability to liquids, gases, moisture, and organic vapors.

• Melting range: 300 to 310 °C (572 to 590 °F)
• Heat sealable
|
| Mechanical Toughness | Long Time Weatherability | Exceptional Flame Resistance |
|
• Superior anti-stick and low frictional properties
• High resistance to impact and tearing
• Useful physical properties at cryogenic temperatures
|
• Inert to outdoor exposure
• High transmittance of ultraviolet and all, but far, infrared
|
Non-flammable (Limiting Oxygen Index >95%) and self-extinguishing. |
