Products labeled PFA 340 and PFA 340 X are equivalent and all information in this document is applicable to both.

 

Typical Application

Applications for DuPont™ 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.

 

DuPont™ 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.

 

Teflon ® PFA 340 meets the requirements of ASTM D3307, Type I
