For inventory control purposes product name may be followed by an X. Products labeled PFA 450HP and PFA 450HP X are equivalent and all information in this document is applicable to both. Typical Application Applications for DuPont™ Teflon ® PFA 450HP include tubing, chemical linings for pipes, valves, and fittings used in the chemical processing industries, unsupported pipe linings for the production of ultra-pure chemicals, semiconductor components, and fluid handling components for high-performance chemical delivery systems where purity in the parts-per-billion range is needed. Teflon ® PFA 450HP is preferred in applications where extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Description DuPont™ Teflon ® PFA 450HP is a special purpose fluoroplastic resin available in pellet form. This resin is a chemically modified form of Teflon ® PFA 350 that combines many of the benefits of the parent resin (highest resistance to environmental stress-cracking with a typical MIT folding endurance of 500,000*) with several additional benefits including enhanced purity, improved thermal stability while processing, and chemical inertness; for example, to ozonated fluids. Table 1 shows the typical property data for Teflon ® PFA 450HP. Teflon ® PFA 450HP is a relatively low melt flow rate (typical MFR of 2), premium resin with the lowest level of extractables designed to meet ultra-high purity requirements. An enhanced resistance to environmental stress-cracking makes Teflon ® PFA 450HP a preferred resin when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Additionally, the enhanced purity of Teflon ® PFA 450 HP makes it suitable for applications that require improved color, lower extractable fluorides, and freedom from other foreign materials. This product contains no additives and is designed for hostile chemical environments where purity in the parts-per-billion range is needed. Examples are in semiconductor manufacture, fluid handling systems for industry or life sciences, and instrumentation for precise measurements of fluid systems. Compared to other thermoplastics, the high melt strength and thermal stability of Teflon ® PFA 450HP can be used to improve processing rates, combining the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® PFA 450HP 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 450HP 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 450HP meets the requirements of ASTM D3307, Type II | ||||
