Products labeled PFA 440HPB and PFA 440HPB X are equivalent and all information in this document is applicable to both. 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, ultimately 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	出于库存控制的目的，产品名称后面可以跟一个X。标记为PFA 340和PFA 340 X的产品是等效的，本文件中的所有信息都适用于这两者。杜邦特氟龙PFA 340的典型应用包括软管、电线和电缆绝缘和套管的挤压管和其他型材；工业薄膜；以及要求具有优异电气、化学和热性能的注塑或压缩成型制品。杜邦特氟隆PFA 340是一种通用的氟塑料树脂，可提供颗粒形式。与其他等级的特氟隆PFA相比，其最独特的特点是相对较高的熔体流动速率（典型的MFR为14）和性能，使其适用于各种工艺和苛刻的最终用途。表1显示了特氟隆PFA 340的典型性能数据。当生产具有氟塑料树脂优良性能的产品需要传统的挤压和成型工艺时，使用特氟隆PFA 340。与其他热塑性塑料相比，聚四氟乙烯PFA340具有较高的熔融强度和热稳定性，可用于提高加工速度。与其他氟塑料相比，耐高温蠕变性能提供了优越的平衡性和最终使用性能。Teflon PFA 340结合了传统热塑性塑料的易加工性，具有许多类似于聚四氟乙烯的特性。由纯聚四氟乙烯PFA 340树脂制成的经过适当加工的产品具有氟塑料树脂的优良特性：化学惰性、优异的介电性能、耐热性、韧性和柔韧性、低摩擦系数、不粘特性、可忽略的吸湿性、低可燃性、性能优异。在极端温度下，具有优异的耐候性。在火焰情况下，特氟隆PFA 340的产品能够抵抗点燃，不促进火焰蔓延。当被其他来源的火焰点燃时，它们的热量贡献很小，并且以很低的烟以缓慢的速度添加。特氟隆PFA 340符合ASTM D3307，I型的要求 For inventory control purposes product name may be followed by an X.

Typical Application Applications for DuPont™ Teflon ® 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. DuPont™ Teflon ® 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. Teflon ® PFA 340 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin.
