Products Information
Everflon FEP Resin E4622
Everflon™ FEP E4622 is a melt-processible fluoroplastic resin available in pellet form. It is a copolymer of tetrafluoroethylene and hexafluoropropylene, without additives, that meets the requirements of ASTM D 2116.
With a relatively high melt flow rate and excellent electrical properties, Everflon™ FEP E4622 has been specifically designed for high-speed extrusion of thin coatings on small-gauge wires for twisted-pair constructions.
This resin provides the electrical and mechanical properties needed for low voltage applications. In addition, Everflon™ FEP E4622 has a higher melt flow rate than most other fluoroplastic resins. This permits higher extrusion speeds and easier processing, making Everflon™ FEP E4622 a cost-effective alternative for producing thin-wall extrusions.
Everflon™ FEP E4622 is designed and made to have improved adhesion to copper wire under specific wireline process conditions, low dissipation factor at high frequencies, and significant plate-out resistance in melt extrusion. It is suitable as a solid insulator and as a foamed insulator, when used with an appropriate nucleant in a nitrogen gas injection process.
Everflon™ FEP E4622 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of Everflon™ FEP E4622 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. Everflon™ FEP E4622 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.
Properly processed products made from neat Everflon™ FEP E4622 resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heatresistance, toughness and flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, lowflammability, performance at temperature extremes, and excellent weather resistance

Application
Applications for Everflon™ FEP E4622 include small diameter, thin wall wire and cable insulation; industrial film; and intricate or thin wall parts made by injection molding.
Processing
Everflon™ FEP E4622 can be processed by conventional melt extrusion, and by injection, compression, and transfer molding processes.
High melt strength and heat stability permit the use of relatively large die openings and high temperature draw-down techniques
that increase production rates. Reciprocating screw injection molding machines are preferred. Corrosion-resistant metals should be
used in contact with molten fluoroplastic resin.
Extruder barrel should be long, relative to diameter, to provide residence time
for heating the resin to approximately 400 °C (750 °F).
Packing & Delivery
Storage&Handing
Everflon FEP resins are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and water condensation on the resin when opening and emptying the packaging.
Package&Caution
Everflon® FEP is packaged in 25kg, single layer, plastic bags. For convenient shipment, orders of 1,000-kg pallets are
recommended.

Everflon FEP
Everflon's FEP
Everflon® FEP is a melt-processible fluoroplastic resin available in pellet form. It is a copolymer of tetrafluoroethylene(TFE) and hexafluoropropylene(HFP), without additives, has a lower melt viscosity than PTFE and can be processed like other thermoplastic resins by the melt flow processes of extrusion, transfer, injection and compression molding. Because the bonding energy between its carbon and fluorine atoms is so high, and the molecule is completely filled with fluorine atoms, Everflon FEP fluorocarbon polymer has excellent thermal, electrical, and chemical stability.
AN EXCELLENT ELECTRICAL INSULATOR
A low dielectric constant and dissipation factor exist along with high dielectric strength over a wide range of frequencies and
temperatures.
temperatures.
LOW FRICTION
Everflon FEP offers the lowest critical surface energy of any plastic material in addition to excellent water and oil repellency for non-stick and mold release applications.
HIGH TRANSPARENCY
Products prepared from Everflon FEP are transparent with good transmittance of both ultraviolet and visible wavelengths; the lowest refractive index of any plastic and characterized by very low light reflection
TOLERANT OF HIGH TEMPERATURES
Everflon FEP offers superior reliability and retention of its properties in a wide thermal range from cryogenic to high
temperature (-200°C to +200°C).
temperature (-200°C to +200°C).
HEALTH APPROVED & FOOD SAFE
This makes it an excellent choice for applications in food manufacturing and packaging, particularly since the material is food grade compliant and resistant to staining.
CHEMICALLY RESISTANT & INERT
Everflon FEP maintains its physical properties in extreme environments. It provides excellent chemical and permeation resistance including exposure to weathering, light, and moisture.
