| 备注说明 | For inventory control purposes product name may be followed by an X.Products labeled PFA TE9724 and PFA TE9724 X are equivalent and all information in this document is applicable to both.Typical ApplicationDuPont™ Teflon ® PFA TE9724 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 compression molded articles requiring superior electrical, chemical, and thermal properties. Teflon ® PFA TE9724 offers a slightly higher melt flow rate than Teflon ® PFA TE9725, providing greater processing ease.DescriptionDuPont™ Teflon ® PFA TE9724 is a general-purpose fluoroplastic resin available as loosely compacted fluff. It is intended for use in special application processes in consultation with DuPont. Compared with other grades of Teflon ® PFA, its most unique features are a relatively high flow rate and properties that make it suitable for a variety of processes and demanding end uses, especially compounding and compression molding. Table 1 shows the typical property data for Teflon ® PFA TE9724.Teflon ® PFA TE9724 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of Teflon ® PFA TE9724 can be used to improve processing rates. Compared with other thermoplastics, Teflon ® PFA TE9724 provides a superior balance and level of end-use properties at high service temperatures. Teflon ® PFA TE9724 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.Properly processed products made from neat Teflon ® PFA TE9724 resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes and excellent weather resistance.In a flame situation, products of Teflon ® PFA TE9724 resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.Teflon ® PFA TE9724 meets the requirements of ASTM D3307, Type I |
