杜邦Tefzel HT-2183含氟聚合物是一种优质树脂,可制成半透明的2.5-mm(0.1-in)颗粒。与其他等级的tefzel相比,其最独特的特点是极大地提高了弹性寿命和抗环境压力。Tefzel HT-2183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-2183是其他热塑性塑料缺乏机械韧性、广泛的热性能、满足异常热、机械和化学环境极限的能力,或受到制造问题限制的应用的首选。例如化学工业的部件和衬里以及高温下使用的带有金属嵌件或厚截面的模件。由纯TEFZEL HT-2183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,水解稳定,耐候。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。它们能够抵抗环境应力开裂,具有优异的冲击强度、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-2183是许多终端产品的理想选择,包括化学服务项目,如衬里阀门和配件、泵壳和叶轮、柱填料和其他耐磨衬里;高温电气部件和绝缘材料;紧固件、波纹管和管道工程;以及薄膜。 DuPont™ Tefzel ® HT-2183 fluoropolymer is a premium resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel ®, its most unique features are a greatly enhanced flex life and resistance to environmental stress. Tefzel ® HT-2183 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-2183 is preferred for applications where other thermoplastics are lacking in mechanical toughness; broad thermal capability; ability to meet unusual thermal, mechanical, and chemical environmental extremes; or limited by fabricating problems. Examples are components and linings for the chemical industry and molded parts with metal inserts or thick sections for use at high temperatures. Properly processed products made from neat Tefzel ® HT-2183 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. The level and stability of dielectric properties are excellent and the flame rating is V-0 by the UL94 method. They are resistant to environmental stress cracking and have outstanding impact strength, cutthrough, 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-2183 is ideal for many end products, including chemical service items, such as lined valves and fittings, pump housings and impellers, column packings, and other abrasion-resistant linings; high-temperature electrical components and insulation; fasteners, corrugated tubing, and duct work; and film. |
