Niche PA66MIBK是一种聚酰胺66（尼龙66）材料,。 该产品在北美洲有供货,。 Niche PA66MIBK的主要特性为:耐冲击。 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 smolke. Teflon" PFA 350 meets the requirements of ASTM D3307, Type ll. |
出于库存控制目的，产品名称后面可以跟一个X。标记为PFA 450HP和PFA 450HP X的产品是等效的，本文档中的所有信息都适用于这两者。杜邦特氟龙PFA 450HP的典型应用包括管道、化学处理工业中使用的管道、阀门和配件的化学衬里、生产超纯化学品的无支撑管道衬里、半导体组件以及高性能化学品输送系统的流体处理组件，其中需要十亿分之一范围内的纯度。特氟隆PFA 450HP是首选的应用，在涉及化学、热和机械应力的恶劣环境中需要扩展服务。说明：杜邦特氟隆PFA450HP是一种特殊用途的氟塑料树脂，颗粒形式。该树脂是特氟隆PFA 350的化学改性形式，它结合了母树脂的许多优点（对环境应力开裂的最大抵抗力，典型的MIT耐折强度为500000*）和其他一些优点，包括提高纯度、提高加工时的热稳定性和化学惰性；以及例如，臭氧化液体。表1显示了特氟隆PFA 450HP的典型性能数据。特氟隆PFA450HP是一种相对较低的熔融流速（典型的MFR为2），优质树脂，具有最低水平的可萃取性，旨在满足超高纯度要求。增强的抗环境应力开裂性能使特氟隆PFA 450HP成为在涉及化学、热和机械应力的恶劣环境中需要延长使用寿命的首选树脂。此外，特氟隆PFA450HP的高纯度使其适用于需要改进颜色、降低可提取氟化物以及不受其他异物影响的应用。本产品不含添加剂，适用于需要十亿分之一纯度的恶劣化学环境。例如半导体制造、工业或生命科学流体处理系统以及流体系统精确测量仪器。与其他热塑性塑料相比，特氟隆PFA450HP的高熔融强度和热稳定性可用于提高加工速度，结合传统热塑性塑料的易加工性和许多类似于聚四氟乙烯的特性。由纯聚四氟乙烯PFA 450HP树脂制成的经过适当加工的产品具有氟塑料树脂的优良性能特征：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、高性能。在极端温度下，具有良好的耐候性。在火焰情况下，特氟龙PFA450HP的产品不着火，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。特氟龙PFA 450HP符合ASTM D3307第二类要求 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 |
