Typical Application
Applications for DuPont™ Teflon ® PFA 440HPB include fluid handling components for critical, high-purity processes like semiconductor, pharmaceutical, and biotechnology, as well as applications where purity in the parts-per-billion range is needed. Teflon ® PFA 440HPB offers a slightly lower melt flow rate than Teflon ® PFA 440HPA, ultimay providing a higher degree of stress-crack resistance.
Description
DuPont™ Teflon ® PFA 440HPB is a special purpose fluoroplastic resin available in pellet form. This resin is a chemically modified form of Teflon ® PFA 340 that combines many of the benefits of the parent resin （a relatively high typical melt flow rate of 14） 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 440HPB.
Teflon ® PFA 440HPB is a premium resin with the lowest level of extractables designed to meet ultra-high purity requirements. Teflon ® PFA 440HPB has a relatively high melt flow rate for injection molding and extrusion processes, and the highest level of inertness due to stable end group polymer structure. The enhanced purity of Teflon ® PFA 440HPB 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 440HPB 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 440HPB 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 440HPB 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 440HPB meets the requirements of ASTM D3307, Type I |
