FEP
Color Concentrates
Compounds
Striping Inks
FEP, like other melt-processible fluoropolymers, is a moderately soft and pliable plastic resin.
It's service temperature is 204° C (400° F). It features a unique combination of electrical
performance, temperature resistance, tribological properties and chemical resistance. FEP is most
commonly used to insulate wires, featuring very low smoke generation and flame propagation
properties and superior dielectric constant/insulation performance. Colorant-Chromatics FEP
compounds provide enhanced properties over unfilled grades of FEP for applications that require
special performance or a combination of performance features.
Titanate fiber reinforced compounds
|
FEP titanate fiber reinforced compounds are chemically inert, with excellent cryogenic and high
temperature physical properties. Typical applications include extruded components where
abrasion resistance and cut through resistance are required. Titanate fiber is a specially
produced ceramic type filler.

Antistatic compounds for static dissipation
|
FEP antistatic compounds are used to dissipate static charges by providing
low levels of conductivity in FEP.

FEP Foam Concentrates
|
FEP foam concentrates contain a finely dispersed nucleating agent.
These concentrates are intended to be let down with FEP resin, providing a polymer mix that
contains a customized nucleating agent concentration. This polymer mix is in turn extruded
into wire insulation or profile shapes creating a construction of foamed FEP. The nucleating
agent in this polymer mix provides nucleating sites for bubble formation during the extrusion
process.
Foamed FEP provides enhanced electrical properties, reduced cable weight, and FEP material
cost. Foamed FEP wire insulations provide a low dielectric constant and a low dissipation
factor that permit high frequency signal transmission with minimal distortion.
With foamed FEP wire insulation, void content of greater than 40% and void cell size on the
order of 30 microns can be achieved.

X-ray opaque FEP compounds
|
These compounds contain various fillers such as barium sulfate that are visible upon exposure
to x-rays. Customized colored compounds are also available.
|
Proprietary Compounds
|
Other compounds made from FEP using special fillers can be made upon request to answer the
needs for special engineering requirements.
|
Extrusion/processing aid
|
Typical processing benefits are: better surface finish, expanded heat processing window,
elimination of die drool and higher line speeds.
