Description
PFA 350 is a general-purpose fluoropolymer resin available in pellet form. Compared with other grades of PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both PFA 340 and PFA 345.

PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. PFA 350 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoropolymer resin. Compared to other thermoplastics, the high melt strength and thermal stability of PFA 350 can be used to improve processing rates. Compared with other fluoropolymers, creep resistance at high service temperatures provides a superior balance and level of end-use properties.PFA 350 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

Typical Applications
Applications for PFA 350 include extruded tubing for use in handling aggressive fluids at high pressures; chemical linings for pipes used in the chemical processing industry; film for high flex service; and traditional extruded, injection-molded, or blowmolded articles requiring the unique performance of Teflon.

Processing
PFA 350 can be processed by conventional melt extrusion, and by injection, compression, transfer, and blow 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 350 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 350 is supplied as pellets and is available in 25-kg multilayer bags with an integral polyethylene liner.
