For inventory control purposes, product name may be followed  by an X. Products labeled PFA 340 and PFA 340 X are equivalent, and all  information in this document is applicable to both. 

Typical Applications  

Applications for Teflon™  PFA 340 include extruded tubing and  other profiles for hose, wire and cable insulation, and sleeving;  industrial film; and injection or compression molded articles  requiring superior electrical, chemical, and thermal properties. 

Description  

Teflon™  PFA 340 is a general-purpose fluoroplastic resin available  in pellet form. Compared with other grades of Teflon™  PFA, its  most unique features are a relatively high melt flow rate (typical  MFR of 14) and properties that make it suitable for a variety of  processes and demanding end uses. Table 1 shows the typical  property data for Teflon™  PFA 340.  

Teflon™  PFA 340 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 340 can be used to improve processing rates.  Compared with other fluoroplastics, creep resistance at high  service temperatures provides a superior balance and level of  end-use properties. Teflon™  PFA 340 combines the processing  ease of conventional thermoplastics with many properties similar  to those of polytetrafluoroethylene.  

Properly processed products made from neat Teflon™  PFA  340 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 340 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.
