ECCtreme™ ECA 3000
Fluoroplastic Resin

Product Information
Description
ECCtreme™ ECA1 3000 fluoroplastic resin is a class of
perfluoroplastic specifically designed for use in extreme
applications requiring an operating temperature ofup to 300 °C (572 °F)2 in combination with excellent
electrical properties and/or chemical resistance.
ECCtreme™ ECA 3000 fluoroplastic resin was developed
in response to industry demand for a melt-extrudable,
high-temperature fluoroplastic resin for wire and cableapplications. ECCtreme™ ECA 3000 fluoroplastic
resin has been recognized as a 300 °C (572 °F) rated
material per UL 746B2 by UL. Compared with ECCtreme™
ECA 4000 fluoroplastic resin, ECCtreme™ ECA 3000
fluoroplastic resin has a lower melt-flow rate (MFR),
making it ideal for constructions needing >10 mil (0.254mm) of insulation. ECCtreme™ ECA 3000 fluoroplastic
resin can also be extruded into rods or tubing, as well as
into compression, injection, and transfer molded parts.
ECCtreme™ ECA 3000 fluoroplastic resin can be meltprocessed using standard high-temperature fluoroplastic
equipment, at standard operating speeds, and possesses
physical, electrical, and chemical properties characteristicof polytetrafluoroethylene (PTFE). Its features include:• UL rated for 300 °C (572 °F)2
• High melting point of 320 °C (608 °F)• Excellent dielectric properties• Excellent chemical and permeation resistance• Broad wire processing window of operation

UL Yellow Card (E54681) for 300 °C (572 °F) rating is based on UL 746B testing; for wireand cable applications, 300 °C (572 °F) rating is referenced in UL 1581 and UL 758.
Not a guarantee of performance; see section “Important Notice” on p. 3

In addition, ECCtreme™ ECA 3000 fluoroplastic resin
demonstrates enhanced properties (e.g., higher meltingpoint, increased melt viscosity, improved stress crackresistance) when subjected to post-processing heat
treatment as shown in the table on p. 3. This effect, known
as epitaxial co-crystallization (ECC), occurs when theresin is heated between 280–300 °C (536–572 °F) for a
prolonged period.

Safety Precautions
WARNING! VAPORS CAN BE LIBERATED THAT MAY BE
HAZARDOUS IF INHALED.
Before using ECCtreme™ ECA 3000 fluoroplastic resin,refer to the Safety Data Sheet and the latest edition
of “The Guide to the Safe Handling of Fluoropolymer
Resins,” published by The Society of the Plastics Industry,
Inc. (www.fluoropolymers.org) or by PlasticsEurope(www.plasticseurope.org).
Open and use containers only in well-ventilated areasusing local exhaust ventilation (LEV). Vapors and fumes
liberated during hot processing of ECCtreme™ ECA 3000
fluoroplastic resin should be exhausted completelyfrom the work area. Contamination of tobacco withthese fluoroplastics must be avoided. Vapors and fumes
liberated during hot processing that are not properly
exhausted, or from smoking tobacco or cigarettes
contaminated with ECCtreme™ ECA 3000 fluoroplastic
resin, may cause flu-like symptoms, such as chills, feverand sore throat. This may not occur until several hours
after exposure and will typically pass within about 24 hr.
Mixtures with some finely divided metals, such as
magnesium or aluminum, can be flammable or explosive
under some conditions.

Storage and Handlingmelt. Corrosion is likely to occur if dead spots exist in
the equipment, processing temperatures are too high,or hold-up time is too long. In addition, resin degradation
will accelerate corrosion. Nickel-based alloys, suchas Hastelloy3, Inconel4, Monel4, and Xaloy5, are thematerials of choice. Hardened nickel plate can be used,
but even small holes, chips, or cracks in the plating cancompromise its performance. Chrome-plated materials
are not recommended. Additional information on materialsof construction can be obtained from your Chemours
representative. Extruder barrels should be long, relative
to diameter, to provide residence time for heating theresin to approximately 390 °C (730 °F). A 1.5- to 2.5-in
extruder with a barrel length to diameter ratio of 24:1
or higher is recommended for larger diameter extruders
and 30:1 for smaller diameter extruders extruding
ECCtreme™ ECA 3000 fluoroplastic resin. Extruder
barrels should have four to five independently controlled
heater zones with temperature controllers capable ofaccurate operation (±0.6 °C [±1 °F]) in the temperature
range of 316–425 °C (600–800 °F). Heaters should
be made of cast bronze or aluminum. Controllers withproportional-integral-derivative (PID) action or equivalent
are recommended. A melt thermocouple and meltpressure probe should be installed in the adapter sectionof the extruder. To obtain an accurate measurement,
the thermocouple should protrude into the melt flow
sufficient to measure its temperature, not the metal
surrounding it.

The properties of ECCtreme™ ECA 3000 fluoroplastic
resin are not affected by storage time. Ambient storage
conditions should be designed to avoid airborne
contamination and water condensation on the resin when
it is removed from containers.

Freight Classification
ECCtreme™ ECA 3000 fluoroplastic resin is classified as“Plastics, Materials, Pellets.”

Packaging
ECCtreme™ ECA 3000 fluoroplastic resin is suppliedin 25 kg, single layer, plastic bags.

Processing Guidelines
ECCtreme™ ECA 3000 fluoroplastic resin can beprocessed by conventional fluoroplastic melt extrusion
and injection, compression, and transfer molding
processes. For wire and cable applications, theprocessing window is large; wire constructions from AWG
30 gauge to AWG 4 gauge with 10–75 mil of insulation
have been produced. ECCtreme™ ECA 3000 fluoroplastic
resin processes best in a typical tubing draw-down
extrusion using the same temperature profile as otherfluoroplastics. Corrosion-resistant metals should be usedin contact with molten fluoroplastic resin. Extruder barrel
should be long, relative to diameter, to provide residence
time for heating the resin.
For more detailed processing information, including
recommended draw-down ratios (DDR) and molding
parameters, consult your Chemours representative. For
recommendations specific to transfer molding, consult
the ECCtreme™ ECA addendum (“Application Processing
Profile for Transfer Molding of ECA ECCtreme™
Fluoroplastics”) to the “Teflon™/Tefzel™ Transfer MoldingGuide.”

Extrusion Equipment
ECCtreme™ ECA 3000 fluoroplastic resin is fabricatedusing the same melt-processing techniques as otherthermoplastics. A brief description of the extrusion
equipment used with ECCtreme™ ECA 3000 fluoroplastic
resin is given here; for more detailed processing
information, consult the Chemours bulletin “Teflon™/Tefzel™ Melt Extrusion Guide,” which can be obtained
from your Chemours representative. Molten fluoroplastic
resins are corrosive to many metals; therefore, special
corrosion-resistant materials must be used for all partsof extrusion equipment that come into contact with theDegradation of the resin during processing greatly
reduces the performance of ECCtreme™ ECA 3000
fluoroplastic resin in stringent applications. Degradation
is caused by excessively high melt temperatures, longresidence time in the extruder, and/or excessive shear
from the screw. In general, increases in the MFR greaterthan 10% during extrusion should be avoided. Other
processing conditions that can reduce the resin’s
performance include melt fracture, very low or unevenmelt temperatures, and the presence of hydrocarbon
or silicone oils, which act as stress-crack promoters.
It is strongly recommended that an ECCtreme™ ECA
3000 fluoroplastic resin-based color concentrate
be selected for custom-colored applications. Use ofalternative materials in the color concentrate could resultin a reduction in the physical properties of ECCtreme™
ECA 3000 fluoroplastic resin, as well as decreasedprocessibility.

techniques. It can be extruded using a wide range ofDDRs; however, high draw-downs generally offer morefavorable processing conditions. The draw ratio balance(DRB) should be in the range of 1.04–1.08. There is acomplete discussion of DDR and DRB, including how
they can be calculated, in the Chemours bulletin, “Teflon™/Tefzel™ Melt Extrusion Guide.” The melt temperature of
the extrudate is critically important to the wire coating

Considerable experimentation has gone into thedevelopment of ECCtreme™ ECA 3000 fluoroplastic resin.
This work has resulted in a resin that when processed
within the recommended processing parameters will
give a reliable, consistent manufacturing process forinsulating wire. ECCtreme™ ECA 3000 fluoroplastic resin
is applied as a wire insulation using tubing extrusion

Fluoroplastic Resinprocess. Melt temperature cannot be reliably predicted bytemperature profiles, as it will also vary with throughput.
Melt temperature should be independently measured byan in-stream probe at the adapter or some other provenreliable means. An electronic wire preheater (or in-line
wire draw annealer), located as close to the crosshead
as possible, is recommended for preheating the wireto 105–176 °C (220–350 °F). A controlled vacuum isrequired at the rear of the crosshead to adjust the melt
cone to the desired length. Experiments have shown cone
lengths from 38–57 mm (1.5–2.25 in) yield satisfactory
results with 80–100 DDR. Stationary pulleys should
be located on both sides of the crosshead to reducewire flutter. The wire should pass through the crosshead
without touching the inside of the head or the extrusion
tooling. Consideration should be given to the use of ashort, hot water bath at the extruder end of the trough.
Processing conditions will depend on the equipmentused, the product being made, and the production rates
needed. Further guidance is available from your Chemours
representative.
