Processing

Typical Applications
Teflon™ PFA 9725 is an ideal resin for applications involving
compounding and compression molding, as well as extruded
tubing and other profiles for hose, electrical insulators, andsleeving; industrial film and products made from film; andinjection or blow-molded articles requiring superior electrical,chemical, and thermal properties. Teflon™ PFA 9725 offers aslightly lower melt flow rate than Teflon™ PFA TE9724, ultimately
providing a higher degree of stress-crack resistance.

Description
Teflon™ PFA 9725 is a general-purpose fluoroplastic resin
available as loosely compacted fluff. It is intended for use in
special application processes in consultation with Chemours.
Compared with other grades of Teflon™ PFA, its most uniquefeatures are a relatively low flow rate and properties that makeit suitable for a variety of processes and demanding end uses,
especially compounding and compression molding. Table 1
shows the typical property data for Teflon™ PFA 9725.
Teflon™ PFA 9725 is used when traditional extrusion andmolding processes are required for producing products with thesuperior properties of a fluoroplastic resin. Compared to otherthermoplastics, the high melt strength and thermal stability ofTeflon™ PFA 9725 can be used to improve processing rates.
Compared with other thermoplastics, Teflon™ PFA 9725 provides
a superior balance and level of end-use properties at high service
temperatures. Teflon™ PFA 9725 combines the processing easeof conventional thermoplastics with many properties similar tothose of polytetrafluoroethylene.
Properly processed products made from neat Teflon™ PFA
9725 resin provide the superior properties characteristic offluoroplastic resins: chemical inertness, exceptional dielectric
properties, heat resistance, toughness and flexibility, lowcoefficient of friction, non-stick characteristics, negligible
moisture absorption, low flammability, performance attemperature extremes, and excellent weather resistance.
In a flame situation, products of Teflon™ PFA 9725 resist ignitionand do not promote flame spread. When ignited by flame fromTeflon™ PFA 9725 can be processed by conventional melt extrusion,and by injection, compression, and transfer molding processes. Highmelt strength and heat stability permit the use of relatively large die
openings and high temperature draw-down techniques that increase
production rates. Reciprocating screw injection molding machines
are preferred. Corrosion-resistant metals should be used in contact
with molten fluoroplastic resin. Extruder barrel should be long,
relative to diameter, to provide residence time for heating the resin
to approximately 390 °C (730 °F). For more detailed processing
information, including recommended draw-down ratios, consult yourChemours sales representative.

Safety Precautions
WARNING! VAPORS CAN BE LIBERATED THAT MAY BE
HAZARDOUS IF INHALED.
Before using Teflon™ PFA 9725 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 wellventilated areas using local exhaust ventilation (LEV). Vapors andfumes liberated during hot processing of Teflon™ PFA 9725 should be
exhausted completely from the work area. Contamination of tobaccowith these polymers must be avoided. Vapors and fumes liberated
during hot processing that are not properly exhausted, or fromsmoking tobacco or cigarettes contaminated with Teflon™ PFA 9725,
may cause flu-like symptoms, such as chills, fever, and sore throat.
This may not occur until several hours after exposure and will typicallypass within about 24 hours. Mixtures with some finely divided metals,
such as magnesium or aluminum, can be flammable or explosive
under some conditions.

Storage and Handling
The properties of Teflon™ PFA 9725 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 Classifications
Teflon™ PFA 9725 resin is classified as “Plastics, Materials, Pellets.”

Packaging
Teflon™ PFA 9725 is available in various kilogram quantities; contact
your Chemours sales representative for more information.
