Product Information
For inventory control purposes, product name may be followed by an X.
Products labeled PFA 945HP Plus and PFA 945HP Plus X are equivalent,
and all information in this document is applicable to both.
Typical Applications
With a typical MIT folding endurance of 800,000* cycles, Teflon™ PFA
945HP Plus is designed to withstand repeated flexing and aggressive
chemical stress-cracking agents. Applications for Teflon™ PFA 945HP Plus
include fluid handling components for high-performance chemical deliverysystems, as well as tubing, unsupported pipe linings for the production ofultra-pure chemicals, and semiconductor components where purity in theparts-per-billion range is critical.
Description
Teflon™ PFA 945HP Plus is a premium fluoroplastic resin available in pellet
form. Teflon™ PFA 945HP Plus possesses the same exceptional chemical
resistance, high purity, and protection against ionic contamination asTeflon™ PFA HP grades with the added benefits of improved flex life
(typical MIT flex of 800,000*) and chemical stress-crack resistance.
Teflon™ PFA 945HP Plus meets the increasingly stringent requirements
for ultra-reliable and non-contaminating parts, as well as unmatched HClpermeation resistance. The improved flex life and chemical resistancewill reduce the cost of ownership of high purity fluid handling systems
by reducing downtime caused by mechanical or chemical stresses.
Additionally, parts molded with Teflon™ PFA 945HP Plus have improved
clarity and a smooth finish, which can further help prevent buildup of
microbial contamination in water handling systems. Table 1 shows thetypical property data for Teflon™ PFA 945HP Plus.
This special purpose resin has a mid-range melt flow rate (typical MFR of7), which permits relatively high extrusion speed and easier processing.
The enhanced resistance to environmental stress-cracking makes Teflon™
PFA 945HP Plus a preferred resin when extended service is requiredin hostile environments involving chemical, thermal, and mechanicalstress. Additionally, the enhanced purity of Teflon™ PFA 945HP Plus
makes it suitable for applications that require improved color, lower
extractable fluorides, and freedom from other foreign materials. This
product contains no additives and is designed for hostile chemical
environments where purity in the parts-per-billion range is needed.
Examples are in semiconductor manufacture, fluid handling systems forindustry or life sciences, and instrumentation for precise measurementsof fluid systems. Teflon™ PFA 945HP Plus combines the processing easeof conventional thermoplastics with the properties similar to those ofpolytetrafluoroethylene.
With Teflon™ PFA 945HP Plus, components can last longer under dynamic
loads and resist damage caused by ozonated fluids and fluorosurfactants.
Combined with excellent chemical, permeation, and stress-crack
resistance, this durability leads to a reduced cost of ownership. The highpurity and fully fluorinated molecule end groups of Teflon™ PFA HP Plus can
reduce contamination to protect process yields.
Properly processed products made from neat Teflon™ PFA 945HP Plus
resin provide the superior properties characteristic of fluoroplastic
resins: chemical inertness, exceptional dielectric properties, heat
resistance, toughness and flexibility, low coefficient of friction, non-stick

characteristics, negligible moisture absorption, low flammability, performanceat temperature extremes, and excellent weather resistance.
In a flame situation, products of Teflon™ PFA 945HP Plus resist ignition anddo not promote flame spread. When ignited by flame from other sources,
their contribution of heat is very small and added at a slow rate with very littlesmoke.
Processing
Teflon™ PFA 945HP Plus 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 380 °C (716 °F). For more detailed
processing information, including recommended draw-down ratios, consult
your Chemours representative. .
Safety Precautions
WARNING! VAPORS CAN BE LIBERATED THAT MAY BE HAZARDOUS IFINHALED.
Before using Teflon™ PFA 945HP Plus resin, refer to the Safety Data
Sheet and the latest edition of “The Guide to the Safe Handling ofFluoropolymer 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 areas using local exhaust
ventilation (LEV). Vapors and fumes liberated during hot processing of Teflon™
PFA 945HP Plus should be exhausted completely from the work area.
Contamination of tobacco with these polymers must be avoided. Vapors andfumes liberated during hot processing that are not properly exhausted, or fromsmoking tobacco or cigarettes contaminated with Teflon™ PFA 945HP Plus,
may cause flu-like symptoms, such as chills, fever, and sore throat. This may
not occur until several hours after exposure and will typically pass within about
24 hours. Mixtures with some finely divided metals, such as magnesium oraluminum, can be flammable or explosive under some conditions.
Food Contact Compliance
Properly processed products made from Teflon™ PFA 945HP Plus resin canqualify for use in contact with food in compliance with FDA Inventory ofEffective Food Contact Substance (FCS) Notification # 948. For details andinformation, please contact your Chemours representative.
Storage and HandlingSpecial product isolation and packaging procedures are usedby Chemours to eliminate external contamination of Teflon™ PFA 945HP Plusresin. Processors also must avoid contamination for successful production ofhigh purity products. The properties of Teflon™ PFA 945HP Plus resin are notaffected by storage time. Ambient storage conditions should be designed toavoid airborne contamination and water condensation on the resin when it isremoved from containers.
Freight Classifications
Teflon™ PFA 945HP Plus resin is classified as “Plastics, Materials, Pellets.”
Packaging
Teflon™ PFA 945HP Plus is supplied as pellets and is available in 25-kg
multilayer bags with an integral polyethylene liner.
