For inventory control purposes, product name may be followed  by an X. Products labeled PFA 9725 and PFA 9725 X are equivalent, and  all information in this document is applicable to both. 

Typical Applications  

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.  

Description  

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. Table 1  shows the typical property data for Teflon™  PFA 9725.  

Teflon™  PFA 9725 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 9725 can be used to improve processing rates.  Compared with other thermoplastics, Teflon™  PFA 9725 provides  a superior balance and level of end-use properties at high service  temperatures. Teflon™  PFA 9725 combines the processing ease  of conventional thermoplastics with many properties similar to  those of polytetrafluoroethylene.  

Properly processed products made from neat Teflon™  PFA  9725 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 9725 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.
