FEP Dispersion / 50% Solid Content / Aqueous Liquid / No PFOA/PI
Everflon® FEP Dispersion D50 is a off-white aqueous with non ionic
surfactant. It provides inertness to nearly all industrial
chemicals and solvents;stability at high temperatures;excellent
dielectric properties; excellent weatherability and no-stick
characteristics, using temperature is between -240°C (-400F) to
200°C (400F). It can be used to impart some the unique properties
of FEP to end products that would be difficult to make using
traditional melt extrusion processes.
Properties of Everflon FEP Dispersions
Everflon® FEP Dispersion can be used to coat or impregnate porous
structures, or to make thin lms. It can be coated and melt bonded
to polytetrafluoroethylene (PTFE) resin or used as a hot melt

FEP Dispersion could be used as anti-sticky coating and fiber
impregnation industry, especially for polyimide film impregnation.
It could be used to replace Dupont () and 3M (Dyneon) dispersion
The aqueous fine-powder dispersion of fluorinated ethylene
propylene with milky or yellowish color, is stabilized by non-ionic
surfactant and has excellent flowing performance if melted. The
products from FEP have outstanding thermal stability, distinctive
chemical inertness, superior electrical insulation, low friction
coefficient, and excellent air aging resistance. And it can be used
at temperature up to 200°C for a long time.
Main Processing Way of Everflon FEP Dispersion D50
Conventional dip or flow techniques can be used for coating or
impregnating high temperature fabrics, fibers,and other products
with Everflon® FEP D50. A FEP resin coating on woven fabrics made
of high-temperatureresistant fibers, can be made by dip coating.
Successive passes may be necessary to build the desired thickness
to produce a smooth, crack-free coating. Each coating layer is
usually dried to remove water (typically at 120 °C [250 °F]), baked
to remove the wetting agent (typically at 270 °C [518 °F]), and
then heated above the crystalline melting point of the resin
particles (approximately 265 °C [509 °F]). If the
Everflon® FEP D50 is being used as a top coat over a PTFE-coated
fabric or other parts, the coating must be heated to melt the PTFE
(approximately 337 °C [639 °F]) to maximize adhesion.
Other solid or liquid ingredients can be added to Everflon® FEP D50

Main Application of Everflon FEP Dispersion D50S
1. PI Film Coating
Everflon® FEP D50 must be properly stored to maximize the stability of the
dispersion. The FEP particles will settle on prolonged standing
and/or on prolonged heating— temperatures above 40 °C (104 °F)
should be avoided.
The dispersion must be protected from freezing,which will cause
The optimum storage temperature range is 7–24°C (45–75 °F). If
dispersions are to be stored for extended periods,
lower-temperature storage is desirable.
For optimal performance, Everflon® FEP D50 should be gently mixed or rolled monthly and prior to use.
Storage and handling areas should be clean.Keep dispersiondrums
closed and clean to avoid both contamination and coagulation by
drying at the liquid surface. High processing temperatures will
cause even very small foreign particles to become visible and/or to
make defects in finished products.
Good housekeeping and careful handling are essential.
