出于库存控制目的，产品名称后面可以跟一个X。标记为PFA 945HP Plus和PFA 945HP 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 945HP PLUS的典型应用具有80万次循环的典型MIT折叠耐久性，能够承受反复弯曲和侵蚀性化学应力开裂剂。Teflon PFA 945HP Plus的应用包括用于高性能化学品输送系统的流体处理组件，以及用于生产超纯化学品的管道、无支撑的管道衬里，以及在十亿分之一范围内的纯度至关重要的半导体组件。说明：杜邦特氟隆PFA 945HP PLUS是一种优质的氟塑料树脂，以颗粒形式提供。Teflon PFA 945HP PLUS具有与Teflon PFA HP等级相同的特殊耐化学性、高纯度和抗离子污染保护，并具有提高弹性寿命（典型的MIT弹性为800000）和耐化学应力开裂的额外优点。Teflon PFA 945HP PLUS满足了对超可靠和无污染部件日益严格的要求，以及无与伦比的HCL渗透阻力。改进的弹性寿命和耐化学腐蚀性将通过减少机械或化学应力引起的停机时间来降低高纯度流体处理系统的拥有成本。此外，用特氟隆PFA 945HP PLUS注塑的零件提高了透明度和光洁度，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 945HP PLUS的典型性能数据。这种特殊用途的树脂有一个中期熔融流速（典型的MFR为7），允许相对较高的挤出速度和更容易的加工。增强的抗环境应力开裂性能使特氟隆PFA 945HP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 945HP PLUS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。特氟隆PFA 945HP 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 945HP 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。结合良好的化学、渗透性和抗应力裂缝性，这种耐久性降低了拥有成本。特氟隆PFA HP PLUS的高纯度、全氟化的分子端基可以减少污染，保护工艺产量。由纯聚四氟乙烯PFA 945HP 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 945HP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 945HP PLUS符合ASTM D3307第六类的要求 For inventory control purposes product name may be followed by an X. Products labeled PFA 945HP Plus and PFA 945HP Plus X are equivalent and all information in this document is applicable to both. Typical Application With a typical MIT folding endurance of 800,000 cycles, DuPont™ Teflon ® PFA 945HP Plus is designed to withstand repeated flexing and aggressive chemical stress-cracking agents. Applications for Teflon ® PFA 945HP 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 critical. Description DuPont™ Teflon ® PFA 945HP Plus is a premium fluoroplastic resin available in pellet form. Teflon ® PFA 945HP 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 (typical MIT flex of 800,000*) and chemical stress-crack resistance. Teflon ® PFA 945HP Plus meets the increasingly stringent requirements for ultra-reliable and non-contaminating parts, as well as unmatched HCl permeation resistance. 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. Additionally, parts molded with Teflon ® PFA 945HP Plus have improved clarity and a 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 945HP Plus. This special purpose resin has a mid-range melt flow rate (typical MFR of 7), which permits relatively high extrusion speed and easier processing. The enhanced resistance to environmental stress-cracking makes Teflon ® PFA 945HP 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 945HP 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 945HP Plus combines the processing ease of conventional thermoplastics with the properties similar to those of polytetrafluoroethylene. With Teflon ® PFA 945HP Plus, components can last longer under dynamic loads and resist damage caused by ozonated fluids and fluorosurfactants. Combined with excellent chemical, permeation, and stress-crack resistance, this durability leads to a reduced cost of ownership. The high purity and fully fluorinated olecule end groups of Teflon ® PFA HP Plus can reduce contamination to protect process yields. Properly processed products made from neat Teflon ® PFA 945HP 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 945HP 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 945HP Plus meets the requirements of ASTM D3307, Type VI

    如何将旧冰箱中的聚氨酯保温材料以工业规模返回到材料循环中，而不是用于发电？克劳斯玛菲、RAMPF、REMONDIS和巴斯夫之间的合作重点是在使用后回收此类废物。

    冰箱使用寿命长。为了确保能源效率和减少二氧化碳排放，世界各地几乎所有的电气制造商都依赖聚氨酯的保温性能。聚氨酯在其使用寿命期间是一种节能产品。然而，在生命周期结束时，当冰箱和聚氨酯硬质泡沫完成其任务时，会发生什么？

    根据欧盟关于废弃电气和电子设备（WEEE）的第2012/19/EU号指令的规定，硬质泡沫最终在处理后被再生。但到目前为止，它主要用于能源目的。据PlasticsEurope称，该工艺可回收聚氨酯生产中所用能量的30%左右，但碳不会保留在材料循环中。这四个合作伙伴将通过使用一种称为解聚的新化学回收工艺来改变这种情况，以获得回收的多元醇。这种多元醇将用于生产聚氨酯材料，形成材料循环回路。

    这种创新工艺非常具有挑战性，必须非常稳定，才能将含有大量杂质的废聚氨酯硬质泡沫可靠地转化为高质量的再生多元醇。四个合作伙伴的初步实验取得了积极成果。

    迄今为止，聚氨酯的化学回收过程主要集中在工业废物，通常来自生产环节。这种工业废物的特点是纯度高，非常有利于回收利用。消费后废物的回收流操作起来要复杂得多，因为它们受到其他类型塑料和金属等外来物质的严重污染。
