Teflon® FEP 160

Technical Information

Description

Teflon® FEP 160 fluoropolymer resin is a meltprocessible

fluoropolymer resin useful for

constructions that require very high stress crack

resistance in primaries or jackets.

As shown in Table 1, this resin provides the

electrical and mechanical properties needed for

low-voltage applications. Teflon® FEP 160 has the

lowest melt flow of any Teflon® FEP fluoropolymer

resin. This high melt viscosity corresponds

to a high molecular weight that is useful for

constructions with very thick walls, that require

exceptional stress crack resistance, or that

experience significant thermal cycling. The low

melt flow, however, substantially reduces the

rate at which Teflon® FEP 160 can be extruded.

Like all Teflon® fluoropolymer resins, Teflon®

FEP 160 offers an excellent combination of

properties: chemical inertness, exceptional

dielectric properties, heat resistance, toughness,

flexibility, low coefficient of friction, non-stick

characteristics, negligible moisture absorption,

low flammability, performance at temperature

extremes, and weather resistance.

Applications

Teflon® FEP 160 is only used in specialized wire

and cable applications that can benefit from its

unusual properties such as its great resistance to

stress cracking. Teflon® FEP 160 can be used as

jacket material for data and telecommunications

cables, for use in air return plenums, but CJ92 has

a much faster processing speed which makes it more

economical for most applications that do not require

the stress crack resistance of Teflon® FEP 160.

Safe Handling

Use of an adequate ventilation system allows safe

processing of Teflon® FEP in extruders at high

temperatures. For further information, refer to

the DuPont bulletin “Teflon® Fluorocarbon

Resin: Safety in Handling and Use,” E-35824-1,

which can be obtained from your DuPont

representative.

Packaging

Teflon® FEP 160 is supplied as pellets and is

available in 55-lb (24.9-kg) multilayer kraft bags

with an integral polyethylene liner.

U.S. Freight Classification

For rail shipments, Teflon® FEP 160 is classified

as “Plastic, Synthetic, OTL, NOIBN;” for truck

shipments as “Plastic Materials, Granules;” and

for express shipments as “Plastics, Synthetic.”
