Description
PFA 340 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of PFA, its most unique features are a relatively high melt flow rate (typical MFR of 14) and properties that make it suitable for a variety of processes and demanding end uses.

PFA 340 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of PFA 340 can be used to improve processing rates.Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties.PFA 340 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

Typical Applications
Applications for PFA 340 include extruded tubing and other profiles for hose, wire and cable insulation, and sleeving; industrial film; and injection or compression molded articles requiring superior electrical, chemical, and thermal properties.

Processing
PFA 340 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. 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 your Chemours sales representative.

Storage and Handling
The properties of PFA 340 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.

Packaging
PFA 340 is supplied as pellets and is available in 25-kg multilayer bags with an integral polyethylene liner.
