PFA
Color Concentrates
Compounds
Striping Inks
PFA, like other melt-processible fluoropolymers, is a moderately soft and pliable plastic resin.
It's service temperature is 260° C (500° F). It features a unique combination of electrical
performance, temperature resistance, tribological properties and chemical resistance. PFA is one
of the most inert melt-processible fluoropolymers on the market today, and offers outstanding
chemical resistance. It can be readily extruded or injection molded. Colorant-Chromatics PFA
compounds provide enhanced properties over unfilled grades of PFA for applications that require
special performance or a combination of performance features.
Titanate fiber reinforced compounds
|
PFA 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. In addition, these compounds can
be injected molded. Parts made from these compounds feature improved tensile strength and
stiffness. Titanate fiber is a specially produced ceramic type filler.

Antistatic compounds for static dissipation
|
PFA antistatic compounds are used to dissipate static charges by providing
low levels of conductivity in PFA.
|
PFA Foam Concentrates
|
PFA foam concentrates contain a finely dispersed nucleating agent.
These concentrates are intended to be let down with PFA 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 PFA . The nucleating agent
in this polymer mix provides nucleating sites for bubble formation during the extrusion
process.
Foamed PFA provides enhanced electrical properties, reduced cable weight, and PFA material
cost. Foamed PFA wire insulations provide a low dielectric constant and a low dissipation
factor that permit high frequency signal transmission with minimal distortion.

X-ray opaque PFA 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 PFA 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.
