Description
PFA 345 is a medium melt flow rate fluoropolymer resin available in pellet form. Compared with PFA 340, it offers increased flex life and greater resistance to environmental stress-cracking.

PFA 345 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 345 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 345 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

Typical Applications
Applications for PFA 345 include extruded tubing, wire and cable insulation, injection molded parts, and chemically resistant linings for bellows, valves, fittings, pipes, pumps, and other fluid-handling components.

Processing
PFA 345 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 345 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 345 is supplied as pellets and is available in 25-kg multilayer bags with an integral polyethylene liner.
