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 451HP和PFA 451HP X的产品是等效的,本文档中的所有信息都适用于这两者。典型应用特氟隆PFA 451HP在要求纯度在十亿分之一范围、表面光滑度和最高化学渗透阻力的应用中是首选的;包括用于生产超纯化学品的管道、无支撑的管道衬里、半导体组件和流体处理组件。高性能化学品输送系统,其中应力抗裂性至关重要。说明杜邦特氟隆PFA 451HP是一种特殊用途的氟塑料树脂,可提供颗粒形式。这种树脂是聚四氟乙烯PFA350的一种化学改性形式,它结合了原树脂的许多优点和其他一些优点。Teflon PFA 451HP通过减小球体尺寸,提高表面光滑度,通过提高Teflon PFA 450HP的结晶度,提高纯度,并在加工过程中提高热稳定性,增强化学渗透阻力。特氟隆PFA 451HP是一种相对较低的熔融流速(典型的MFR为2),优质树脂,具有最低水平的可提取物,旨在满足超高纯度要求。增强的耐环境应力开裂和化学渗透性能使特氟隆PFA 451HP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时成为首选树脂。此外,特氟隆PFA 451HP的纯度提高,使其适用于需要改进颜色、降低可提取氟化物和无其他异物的应用。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PFA 451HP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,其许多特性与聚四氟乙烯相似。由纯聚四氟乙烯PFA 451HP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,特氟隆PFA 451HP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。Teflon PFA 451HP符合ASTM D3307第二类的要求 For inventory control purposes product name may be followed by an X. Products labeled PFA 451HP and PFA 451HP X are equivalent and all information in this document is applicable to both. Typical Application Teflon ® PFA 451HP is preferred in applications where purity in the parts-per-billion range, surface smoothness, and the highest levels of chemical permeation resistance are required; including tubing, unsupported pipe linings for the production of ultra-pure chemicals, semiconductor components, and fluid handling components for high-performance chemical delivery systems where stress-crack resistance is critical. Description DuPont™ Teflon ® PFA 451HP 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 advantages of the parent resin with several additional benefits. Teflon ® PFA 451HP exhibits improved surface smoothness achieved through minimization of spherulite size, enhanced chemical permeation resistance achieved by increasing its crystallinity from Teflon ® PFA 450HP, enhanced purity, and improved thermal stability while processing. Teflon ® PFA 451HP 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 and chemical permeation make Teflon ® PFA 451HP a preferred resin when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Additionally, the enhanced purity of Teflon ® PFA 451HP 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 451HP 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 451HP 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 451HP 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 451HP meets the requirements of ASTM D3307, Type II |
