Typical Application
Teflon ™ PFA 9724 is an ideal resin for applications involvingcompounding and compression molding, as well as extruded tubing andother profiles for hose, electrical insulators, and sleeving;industrial film and products made from film; and injection orcompression molded articles requiring superior electrical,chemical, and thermal properties. Teflon ™ PFA 9724 offers aslightly higher melt flow rate than Teflon ™ PFA TE9725, providinggreater processing ease. .
Description
Teflon ™ PFA 9724 is a general-purpose fluoroplastic resinavailable as loosely compacted fluff. It is intended for use inspecial application processes in consultation with Chemours.Compared with other grades of Teflon ™ PFA, its most uniquefeatures are a relatively high flow rate and properties that makeit suitable for a variety of processes and demanding end uses,especially compounding and compression molding. Table 1 shows thetypical property data for Teflon ™ PFA 9724.
Teflon ® PFA TE9724 is used when traditional extrusion andmolding processes are required for producing products with thesuperior properties of a fluoroplastic resin. Compared to otherthermoplastics, the high melt strength and thermal stability ofTeflon ® PFA TE9724 can be used to improve processing rates.Compared with other thermoplastics, Teflon ® PFA TE9724 provides asuperior balance and level of end-use properties at high servicetemperatures. Teflon ® PFA TE9724 combines the processing ease ofconventional thermoplastics with many properties similar to thoseof polytetrafluoroethylene.
Properly processed products made from neat Teflon ® PFA TE9724resin provide the superior properties characteristic offluoroplastic resins: chemical inertness, exceptional dielectricproperties, heat resistance, toughness and flexibility, lowcoefficient of friction, non-stick characteristics, negligiblemoisture absorption, low flammability, performance at temperatureextremes and excellent weather resistance.
In a flame situation, products of Teflon ® PFA TE9724 resistignition and do not promote flame spread. When ignited by flamefrom other sources, their contribution of heat is very small andadded at a slow rate with very little smoke.
Teflon ® PFA TE9724 meets the requirements of ASTM D3307, TypeI
