Description
PFA 416HP is a special purpose fluoroplastic resin available in pellet 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 PFA 416HP a costeffective alternative for producing thin-wall and complicated articles.
Typical Applications
Applications for PFA 416HP include high performance thinwall wire coatings; intricate injection molded parts for production of chemicals where purity in the parts-per-billion range is needed; semiconductor components and electronic parts; and fluid handling systems for high performance chemical filters. With a typical melt flow rate (MFR) of 42, PFA 416HP resin is ideally suited for applications requiring a high processing speed and very low viscosity.
Processing
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.
Storage and Handling
Special product isolation and packaging procedures are used to eliminate external contamination of PFA 416HP resin. Processors also must avoid contamination for successful production of high purity products. The properties of PFA 416HP 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.
