牌号简介	杜邦Tefzel® HT-2185氟聚合物树脂是一种特殊用途的树脂，可制成半透明的2.5-mm（0.1-in）颗粒。与其他等级的tefzel相比，它具有更高的流速。Tefzel® HT-2185和其他Tefzel含氟聚合物是乙烯和四氟乙烯的熔融加工改性共聚物。它们是高性能树脂，与氟碳树脂相比，可以以相对较高的速度加工。它们的机械强度很高，性能达到了很好的平衡。相对较高的流速Tefzel® HT-2185使其特别适用于高速加工，尤其适用于细长、薄壁或复杂形状的挤压涂层和注塑成型。由Tefzel® HT-2185制成的模压或挤压产品最好用于在高温下不涉及显著弯曲或拉伸应力的用途。更高粘度的产品，如tefzel ht-2181和tefzel ht-2183是这些应用的首选。由纯Tefzel® HT-2185制成的经过适当处理的产品对大多数溶剂和化学品都是惰性的，具有水解稳定性和耐候性。建议的最高工作温度为150°C（302°F）；有用的性能保持在低温范围内。采用UL94方法，介电性能稳定，火焰等级为V-0。机械性能包括出色的冲击强度、穿透性和耐磨性。与火焰情况下的行为相关的声明或数据不旨在反映实际火灾条件下该材料或任何其他材料所带来的危险。典型的终端产品TEFZEL HT-2185是许多终端产品的理想选择，包括电气部件，如套管、线圈、插座、连接器和开关；实验室设备，如管道、阀门、容器和紧固件；需要化学惰性的电池或仪器部件；以及机械部件。 DuPont™ Tefzel® HT-2185 fluoropolymer resin is a special-purpose resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel®, it has a higher flow rate. Tefzel® HT-2185 and the other Tefzel® fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high-performance resins that can be processed at relatively high rates compared with fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties. The relatively high flow rate of Tefzel® HT-2185 makes it uniquely suitable for high-speed processing, especially for extruded coatings and injection molding of slender, thin-walled, or intricate shapes. Molded or extruded products made from Tefzel® HT-2185 are preferred for uses that do not involve significant flexural or tensile stress at elevated temperatures. Higher viscosity products such as Tefzel® HT-2181 and Tefzel® HT-2183 are preferred for these applications. Properly processed products made from neat Tefzel® HT-2185 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The recommended upper service temperature is 150°C (302°F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent, and the flame rating is V-0 by the UL94 method. Mechanical properties include outstanding impact strength, cut-through, and abrasion resistance. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions. Typical End Products Tefzel ® HT-2185 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, such as tubing, valves, containers, and fasteners; battery or instrument components that require chemical inertness; and mechanical parts.	杜邦Tefzel® HT-2181氟聚合物树脂是一种通用树脂，可提供半透明的2.5-mm（0.1-in）颗粒。与其他等级的tefzel相比，它最独特的特点是中间流速和平衡性能，使其适合各种工艺和苛刻的最终用途。Tefzel® HT-2181和其他Tefzel含氟聚合物是乙烯和四氟乙烯的熔融加工改性共聚物。它们是高性能树脂，与其他氟碳树脂相比，可以以相对较高的速度加工。它们的机械强度很高，性能达到了很好的平衡。Tefzel® HT-2181能够成功地应用于其他热塑性塑料缺乏机械韧性、广泛的热性能、满足困难环境条件的能力或制造问题所限制的应用。由纯Tefzel® HT-2181制成的经过适当处理的产品对大多数溶剂和化学品都是惰性的，具有水解稳定性和耐候性。建议的最高工作温度为155°C（311°F）；有用的性能保持在低温范围内。采用UL94方法，介电性能稳定，火焰等级为V-0。机械性能包括出色的冲击强度、穿透性和耐磨性。与火焰情况下的行为相关的声明或数据不旨在反映实际火灾条件下该材料或任何其他材料所带来的危险。典型的终端产品TEFZEL HT-2181适用于许多终端产品，包括电气组件，如套管、线圈、插座、连接器和开关；实验室设备，如管道、阀门、容器和盘子；需要化学惰性的电池或仪器组件；化学服务项目，如阀门组件、密封玻璃。NDS、管塞和波纹管；以及薄膜。 DuPont™ Tefzel® HT-2181 fluoropolymer resin is a general-purpose resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel® , its most unique features are an intermediate flow rate and a balance of properties that make it suitable for a variety of processes and demanding end uses. Tefzel® HT-2181 and the other Tefzel® fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high-performance resins that can be processed at relatively high rates compared with other fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties. Tefzel® HT-2181 can perform successfully in applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet difficult environmental conditions, or limited by fabricating problems. Properly processed products made from neat Tefzel® HT-2181 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The recommended upper service temperature is 155°C (311°F); useful properties are retained at cryogenic ranges.
