DuPont PFA 340 / 340 X (340X) Resin

PFA 340/ 340 X
DuPont™ 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.

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 .
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.
Typical Application
Applications for DuPon 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.
