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. 與典型值比較 - Upgrade to compare! 與黃卡比較單位: SI 總覽材料狀態(tài)已商用：當(dāng)前有效資料 1Technical Datasheet (English)UL 黃卡 2E5468搜索 UL 黃卡The Chemours CompanyTefzel?供貨地區(qū)北美洲拉丁美洲歐洲亞太地區(qū)特性Excellent Weather Resistance高抗撞擊性共聚物抗溶劑性良好的電氣性能流動性高耐化學(xué)品性能，良好耐磨損性，良好韌性良好水解穩(wěn)定用途薄壁部件電氣/電子應(yīng)用領(lǐng)域閥門/閥門部件管件緊固件開關(guān)連接器容器實驗室器具外觀半透明形式粒子加工方法吹塑成型擠出擠出涂層樹脂傳遞成型壓縮模塑注射成型物理性能額定值單位制測試方法密度 / 比重1.70g/cm3ASTM D792熔流率（熔體流動速率） (297°C/5.0 kg)30g/10 minASTM D3159吸水率 (24 hr)7.0E-3%ASTM D570機(jī)械性能額定值單位制測試方法抗張強(qiáng)度 (23°C)40.0MPaASTM D3159伸長率 (斷裂, 23°C)300%ASTM D3159彎曲模量 (23°C)1030MPaASTM D790沖擊性能額定值單位制測試方法懸壁梁缺口沖擊強(qiáng)度 (23°C)無斷裂ASTM D256熱性能額定值單位制測試方法熔融溫度255 到 280°CASTM D3159最高使用溫度150°CUL 746電氣性能額定值單位制測試方法體積電阻率1.0E+17ohms·cmASTM D257介電強(qiáng)度 (0.250 mm)67kV/mmASTM D149介電常數(shù) (23°C, 1 MHz)2.60 到 2.80ASTM D150耗散因數(shù) (23°C, 1 MHz)9.0E-3ASTM D150可燃性額定值單位制測試方法極限氧指數(shù)30 到 32%ASTM D2863
