Typical Application
Applications for DuPont™ Teflon ® PFA 350 include extruded tubing for use in handling aggressive fluids at high pressures; chemical linings for pipes used in the chemical processing industry; film for high flex service; and traditional extruded, injection-molded, or blow-molded articles requiring the unique performance of Teflon ® .
Description
DuPont™ Teflon ® PFA 350 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of Teflon ® PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both Teflon ® PFA 340 and 345 (Teflon ® PFA 350 has a typical MIT folding endurance of 500,000*, compared to that of 15,000 and 50,000 for Teflon ® PFA 340 and 345 respectively). Teflon ® PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for Teflon ® PFA 350.
Teflon ® PFA 350 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 350 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 350 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.
Properly processed products made from neat Teflon ® PFA 350 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 350 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 350 meets the requirements of ASTM D3307, Type III
