| 出于库存控制目的，产品名称后面可能会有一个X。标记为PFA 951HP PLUS和PFA 951HP PLUS 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 951HP PLUS具有比标准PFA高达60%的渗透阻力的典型应用设计用于减少化学渗透、抗应力开裂和表面光滑度对减少污染和保护工艺产量至关重要的应用。Teflon PFA 951HP PLUS的应用包括高性能化学品输送系统的流体处理部件，以及生产超纯化学品的管道、无支撑的管道衬里，以及需要纯度在十亿分之一范围内的半导体部件。说明杜邦特氟隆PFA 951HP PLUS是一种优质的氟塑料树脂，以颗粒形式提供。特氟隆PFA 951HP PLUS具有与特氟隆PFA HP等级相同的特殊耐化学性、高纯度和抗离子污染保护，具有提高弯曲寿命和耐化学应力开裂的额外好处。特氟隆PFA 951HP PLUS具有无与伦比的HCl渗透阻力，对氮的渗透性也比其他PFA低45%（氮渗透是其他分子渗透速率的一般指标）。此外，通过减少机械或化学应力引起的停机时间，改进的弹性寿命和耐化学性将降低拥有高纯度流体处理系统的成本。用特氟隆PFA 951HP PLUS成型的零件具有异常光滑的表面，这有助于防止水处理系统中微生物污染的累积。表1显示了特氟隆PFA 951HP PLUS的典型性能数据。特氟隆PFA 951HP PLUS是一种相对较低的熔融流速（典型的MFR为2），专用树脂，具有最低水平的可提取物，旨在满足超高纯度要求。增强的抗环境应力开裂性能使特氟隆PFA 951HP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 951HP PLUS的纯度提高，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。特氟隆PFA 951HP PLUS结合了传统热塑性塑料的易加工性，其性能与聚四氟乙烯相似。使用特氟隆PFA 951HP PLUS，组件在动态负载下可使用更长时间，并可抵抗臭氧化液体和氟表面活性剂造成的损坏。结合特殊的化学、渗透和抗应力开裂性能，这种耐久性降低了拥有成本。特氟隆PFA 951HP PLUS的高纯度、全氟化分子端基可以减少污染，保护工艺收率。由纯聚四氟乙烯PFA 951HP PLUS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。在极端温度下的性能和出色的耐候性。在火焰情况下，特氟龙产品PFA 951HP加上阻燃剂，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 951HP PLUS符合ASTM D 2116-07（2012），V型的要求 For inventory control purposes product name may be followed by an X. Products labeled PFA 951HP Plus and PFA 951HP Plus X are equivalent and all information in this document is applicable to both. Typical Application With permeation resistance that is up to 60% greater than standard PFA, DuPont™ Teflon ® PFA 951HP Plus is designed for applications where reduced chemical permeation, resistance to stress-cracking, and surface smoothness are critical to reducing contamination and protecting process yields. Applications for Teflon ® PFA 951HP Plus include fluid handling components for high-performance chemical delivery systems, as well as tubing, unsupported pipe linings for the production of ultra-pure chemicals, and semiconductor components where purity in the parts-per-billion range is needed. Description DuPont™ Teflon ® PFA 951HP Plus is a premium fluoroplastic resin available in pellet form. Teflon ® PFA 951HP Plus possesses the same exceptional chemical resistance, high purity, and protection against ionic contamination as Teflon ® PFA HP grades with the added benefits of improved flex life and chemical stress-crack resistance. Teflon ® PFA 951HP Plus has unmatched HCl permeation resistance, and is also 45% less permeable to nitrogen than other PFAs (permeation by nitrogen is a general indication of the rate of permeation by other molecules). Additionally, the improved flex life and chemical resistance will reduce the cost of ownership of high purity fluid handling systems by reducing downtime caused by mechanical or chemical stresses. Parts molded with Teflon ® PFA 951HP Plus have an xceptionally smooth finish, which can further help prevent buildup of microbial contamination in water handling systems. Table 1 shows the typical property data for Teflon ® PFA 951HP Plus. Teflon ® PFA 951HP Plus is a relatively low melt flow rate (typical MFR of 2), special purpose resin with the lowest level of extractables designed to meet ultra-high purity requirements. The enhanced resistance to environmental stress-cracking makes Teflon ® PFA 951HP Plus a preferred resin when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Additionally, the enhanced purity of Teflon ® PFA 951HP Plus 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. Teflon ® PFA 951HP Plus combines the processing ease of conventional thermoplastics with the properties similar to those of polytetrafluoroethylene. With Teflon ® PFA 951HP Plus, components can last longer under dynamic loads and resist damage caused by ozonated fluids nd fluorosurfactants. Combined with exceptional chemical, permeation, and stress-crack resistance, this durability leads to a reduced cost of ownership. The high purity and fully fluorinated molecule end groups of Teflon ® PFA 951HP Plus can reduce contamination to protect process yields. Properly processed products made from neat Teflon ® PFA 951HP Plus 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 951HP Plus 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 951HP Plus meets the requirements of ASTM D 2116-07(2012), Type V |
