FEP

Get to know Everflon™ FEP.

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.

Chemical Resistance	Thermal Stability	Electrical Insulation

Why is Everflon™ FEP.
Virtually inert to most chemicals, solvents, and acids, with exceptions like molten alkali metals or certain halogenated compounds.	Excellent service range from cryogenic temperatures (around -400°F / -250°C) up to about 400°F (200°C) and higher for short periods.	• Continuous service temperature: –240 to 260 °C (–400 to 500 °F) • Melting range: 300 to 310 °C (572 to 590 °F) • Heat sealable
Low Friction & Non-Stick	Weathering	Mechanical
Very low coefficient of friction (similar to PTFE) and excellent non-stick properties.	Outstanding resistance to UV, ozone, and sunlight.	Good flexibility, high tensile strength (e.g., ~2100-4350 psi), high elongation (240-325%), and excellent impact strength (no break).
Optical	Flammability	Other
High transparency for visible and UV light (up to 98%).	Non-flammable (V-0 UL 94 rating) with a high oxygen index (>95%).	Low moisture absorption (<0.1%), biocompatible, and FDA-approved.
