Get to Know FEP 4601

Everflon™ FEP 4601 fluoropolymer resin is a meltprocessible fluoropolymer resin useful forconstructions that require very high stress crackresistance in primaries or jack-ets.This resin provides theelectrical and mechanical properties needed forlow-volt-age applications. Everflon™ FEP 4601 has thelowest melt flow of any Everflon™ FEP fluoropolymer resin. This high melt viscosi-ty correspondsto a high molecular weight that is useful forconstructions with very thick walls, that requireexceptional stress crack resistance, or thatexperience signifi-cant thermal cycling. The lowmelt flow, however, substantially reduces therate at which Everflon™ FEP 4601 can be extrud-ed.Like all Everflon™ fluoropolymer resins, Everflon™ FEP 4601 offers an excellent combination ofproperties:

chemical inertness,
exceptionaldielectric properties,
heat resistance,
toughness,
flexibility,
low coefficient of friction,
non-stickcharacteristics,
negligible moisture absorption,
low flammability,
performance at temperatureextremes,
and weather resistance.

Typical Applications

Everflon™ FEP 4601 is only used in specialized wireand cable applications that can benefit from itsunusual prop-erties such as its great resistance tostress cracking. Everflon™ FEP 4601 can be used asjacket material for data and telecommunicationscables, for use in air return plenums, but Everflon™ FEP 4610 has a much faster processing speed which makes it moreeconomical for most applications that do not requirethe stress crack resistance of Everflon™ FEP 4601.

Processing Guide

Everflon™ FEP fluoroplastic resin can be processed by conventional melt extrusion, and by injection, compression, and blow molding processes.

For smooth feeding to extrusion equipment, it is supplied in 3 mm (0.12 in) pellets.

The extruders and molding machines used for Everflon™ FEP should be constructed of high nickel alloy corrosion-resistant materials and be capable of operating at temperatures up to 400 °C (750 °F)

Precaution

Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to com-pletely remove all fumes and vapors from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before process-ing any fluoroplastics, read the Material Safety Data Sheet.
