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. 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-2181 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 dishes; battery or instrument components that require chemical inertness; chemical service items, such as valve components, seal glands, pipe plugs, and corrugated tubing; and film. |

美国的塑料垃圾正在大幅涌向西北亚地域
2018-10-18 去年7月,中国政府宣布禁止进口4大类24种洋垃圾,一年多时间过去取得显著成效。据英媒报道,禁令出台后,中国昔日的进口垃圾重要来源地――美国的塑料垃圾正在大幅涌向东南亚地区的发展中国家。 国际环保机构――“绿色和平组织”(Greenpeace)当地时间10月5日发布了一份调查报告,报告称,美国正在“剥削”(exploiting)那些缺乏监管制度来确保塑料垃圾以环保方式处理的发展中国家。 塑料垃圾涌向东南亚,环保组织报告批:美国正“剥削”这些国家 |
