For inventory control purposes, product name may be followed by an X.
Products labeled PFA 350 and PFA 350 X are eguivalent, and all information in this document is applicable to both.
Typical Application:
Applications for 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 reguiring the unigue performance of Teflon".
Description:
Teflonil PFA 350 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of Teflon PFA, its most unigue features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both Teflonw PFA B40 and S45 (Teflon PEA 350 has a typical MlTfolding endurance of 500,000*, compared to that of 15,000 and 50,000 for Tefloni" PFA 340 and 345, respectively). Teflonw PFA B50 is preferred when extended service is reguired in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for Teflonl" PFA S50.
Teflon PFA 350 is used when traditional extrusion and molding processes are reguired 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.
