Tefzel® 207Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours CompanyTefzel ™ ETFE 207 is a special-purpose fluoroplastic resin available in translucent, 2.5-mm (0.1-in) pellets. Compared with other grades of Tefzel ™ , it has a higher flow rate and still maintains a service temperature of 150 °C (302 °F).Tefzel ® 207 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 ® 207 makes it uniquely suitable for high-speed processing, especially for extruded coatings and injection molding of slender, thin-walled or intricate shapes. Properly processed products made from neat Tefzel ® 207 are inert to most solvents and chemicals, hydrolytically stable, and weather resistant. 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 ProductsTefzel ® 207 is ideal for many end products, including electrical compo
nents such as sleeving, coil forms, sockets, connectors, and switches; lab ware such as tubing, valves, containers, and fasteners; battery or instrument compo
nents that require chemical inertness; and mechanical parts. The high melt flow rate of this product makes it ideal for injection molding and thin wall extrusion. 与典型值比较 - Upgrade to compare! 与黄卡比较单位: SI 总览材料状态已商用：当前有效资料 1Technical Datasheet (English)UL 黄卡 2E5468搜索 UL 黄卡The Chemours CompanyTefzel®供货地区北美洲拉丁美洲欧洲亚太地区特性Excellent Weather Resistance高抗撞击性共聚物抗溶剂性良好的电气性能流动性高耐化学品性能，良好耐磨损性，良好韧性良好水解稳定用途薄壁部件电气/电子应用领域阀门/阀门部件管件紧固件开关连接器容器实验室器具外观半透明形式粒子加工方法吹塑成型挤出挤出涂层树脂传递成型压缩模塑注射成型物理性能额定值单位制测试方法密度 / 比重1.70g/cm³ASTM D792熔流率（熔体流动速率） (297°C/5.0 kg)30g/10 minASTM D3159吸水率 (24 hr)7.0E-3%ASTM D570机械性能额定值单位制测试方法抗张强度 (23°C)40.0MPaASTM D3159伸长率 (断裂, 23°C)300%ASTM D3159弯曲模量 (23°C)1030MPaASTM D790冲击性能额定值单位制测试方法悬壁梁缺口冲击强度 (23°C)无断裂ASTM D256热性能额定值单位制测试方法熔融温度255 到 280°CASTM D3159最高使用温度150°CUL 746电气性能额定值单位制测试方法体积电阻率1.0E+17ohms·cmASTM D257介电强度 (0.250 mm)67kV/mmASTM D149介电常数 (23°C, 1 MHz)2.60 到 2.80ASTM D150耗散因数 (23°C, 1 MHz)9.0E-3ASTM D150可燃性额定值单位制测试方法极限氧指数30 到 32%ASTM D2863
