Chemours Teflon™ PFA 9725 Molding and Extrusion Resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Perfluoroalkoxy (PFA); Polyperfluoroalkoxyethylene, Molded/Extruded
Material Notes:	Teflon™ PFA 9725 is a general-purpose fluoroplastic resin available as loosely compacted fluff. It is intended for use in special application processes in consultation with Chemours. Compared with other grades of Teflon™ PFA, its most unique features are a relatively low flow rate and properties that make it suitable for a variety of processes and demanding end uses, especially compounding and compression molding. Teflon™ PFA 9725 is an ideal resin for applications involving compounding and compression molding, as well as extruded tubing and other profiles for hose, electrical insulators, and sleeving; industrial film and products made from film; and injection or blow-molded articles requiring superior electrical, chemical, and thermal properties. Teflon™ PFA 9725 offers a slightly lower melt flow rate than Teflon™ PFA TE9724, ultimately providing a higher degree of stress-crack resistance. Information provided by Chemours.
