Teflon™ PFA 416HP
Molding and Extrusion Resin

Product Information
For inventory control purposes, product name may be followed by an X.

Processing

Products labeled PFA 416 HP and PFA 416 HP X are equivalent, and all
information in this document is applicable to both.

Teflon™ PFA 416HP can be processed by conventional melt extrusion,and by injection, compression, and transfer molding processes. High melt
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. Corrosionresistant 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
your Chemours sales representative.

Typical Applications
Applications for Teflon™ PFA 416HP include high performance thinwall wire coatings; intricate injection molded parts for productionof chemicals where purity in the parts-per-billion range is needed;
semiconductor components and electronic parts; and fluid handlingsystems for high performance chemical filters. With a typical melt
flow rate (MFR) of 42, Teflon™ PFA 416HP resin is ideally suited for
applications requiring a high processing speed and very low viscosity.

Description
Teflon™ PFA 416HP is a special purpose fluoroplastic resin available inpellet form. This resin has a higher melt flow rate (typical MFR of 42)
than most other PFA fluoroplastic resins, which permits higher extrusion
speed and easier processing, making Teflon™ PFA 416HP a costeffective alternative for producing thin-wall and complicated articles.
Unlike other high melt flow rate polymers, Teflon™ PFA 416HP is speciallyformulated to provide a high melt flow rate for processing ease, while still
providing good flexural properties and stress-crack resistance. These
unique properties, coupled with the resin’s high thermal stability, enablethin coatings of ultra-fine wires and injection molding of complex parts.
Table 1 shows the typical property data for Teflon™ PFA 416HP.
The enhanced purity of Teflon™ PFA 416HP makes it suitable forapplications that require improved color, lower extractable fluorides, andfreedom from other foreign materials. Teflon™ PFA 416HP contains noadditives and is designed for hostile chemical environments where purity
in the parts-per-billion range is needed. Teflon™ PFA 416HP combines theprocessing ease of conventional thermoplastics with many properties similar
to those of polytetrafluoroethylene. Compared to other thermoplastics, thehigh melt strength and thermal stability of Teflon™ PFA 416HP can be used
to improve processing rates, and allows intricate electronics to be insulatedwith an extremely thin coating and still withstand soldering.
Properly processed products made from neat Teflon™ PFA 416HP resin
provide the superior properties typical of the fluoroplastic resins: chemicalinertness, exceptional dielectric properties, heat resistance, toughness
and flexibility, low coefficient 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 416HP resist ignition and do
not promote flame spread. When ignited by flame from other sources, theircontribution of heat is very small and added at a slow rate with very little smoke.

Safety Precautions
WARNING! VAPORS CAN BE LIBERATED THAT MAY BE HAZARDOUS IF INHALED.
Before using Teflon™ PFA 416HP resin, refer to the Safety Data Sheet andthe 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 onlyin well-ventilated areas using local exhaust ventilation (LEV). Vapors and fumes
liberated during hot processing of Teflon™ PFA 416HP should be exhausted
completely from the work area. Contamination of tobacco with these polymers
must be avoided. Vapors and fumes liberated during hot processing that are notproperly exhausted, or from smoking tobacco or cigarettes contaminated with
Teflon™ PFA 416HP, may cause flu-like symptoms, such as chills, fever, and sorethroat. 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.

Food Contact Compliance
Properly processed products made from Teflon™ PFA 416HP resin can qualify
for use in contact with food in compliance with FDA 21 CFR 177.1550 andEuropean Regulation (EU) No 10/2011. For details and information, pleasecontact your Chemours sales representative.

Storage and HandlingSpecial product isolation and packaging procedures are used by Chemours
to eliminate external contamination of Teflon™ PFA 416HP resin. Processors
also must avoid contamination for successful production of high purity
products. The properties of Teflon™ PFA 416HP resin are not affected bystorage time. Ambient storage conditions should be designed to avoid
airborne contamination and water condensation on the resin when it isremoved from containers.

Freight Classifications
Teflon™ PFA 416HP resin is classified as “Plastics, Materials, Pellets.”

Packaging
Teflon™ PFA 416HP is supplied as pellets and available in 25-kg multilayerbags with an integral polyethylene liner.

Definition of continuous service temperature: The continuous service temperature is based on accelerated heat-aging tests, and represents the temperature at which tensile strength andultimate elongation retain 50% of the original values after 20,000 hr thermal aging. Continuous service temperature above 260 °C (500 °F) may be feasible, depending on such factors
as chemical exposure, support from the substrate, etc. When considering uses of Teflon™ PFA 416HP above 260 °C (500 °F), preliminary testing should be done to verify suitability.
† These results are based on laboratory tests under controlled conditions and do not reflect performance under actual fire conditions; current rating is a typical theoretical value.

Typical properties are not suitable for specification purposes.
Statements or data regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions.
