Tefzel? 美國科慕ETFE HT-2202 卡扣 管材應(yīng)用 乙烯四氟乙烯共聚物Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours CompanyDescriptionTefzel ? ETFE HT-2202 is a special-purpose fluoroplastic resin available in 2.5-mm (0.1-in) pellets. Tefzel ? ETFE HT-2202 is a modified ETFE resin designed to promote adhesion between polyamide resins and ETFE resins.Tefzel ? ETFE HT-2202 and the other Tefzel ? fluoroplastics 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.Tefzel ? ETFE HT-2202 is an easy-to-process adhesive material. Tefzel ? ETFE HT-2202 is inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. Recommended upper service is 150 °C (302 °F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent. Mechanical properties include outstanding high-impact strength, cut-through, and abrasion resistance.Typical End ProductsTefzel ? ETFE HT-2202 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors, and switches; lab ware, multi-layer tubing, valves, containers, and fasteners; battery or instrument components that require chemical inertness; and mechanical parts. 與典型值比較 - Upgrade to compare!單位: SI 總覽材料狀態(tài)已商用：當(dāng)前有效資料 1Technical Datasheet (English)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)特性高抗撞擊性良好的柔韌性流動性高耐候性，良好耐化學(xué)品性能，良好耐磨損性，良好水解穩(wěn)定用途電氣/電子應(yīng)用領(lǐng)域閥門/閥門部件管件機(jī)器/機(jī)械部件緊固件開關(guān)連接器容器實(shí)驗(yàn)室器具形式粒子加工方法Transfer Molding吹塑成型擠出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)7.0g/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)34.5MPaASTM D638伸長率 (斷裂, 23°C)250%ASTM D638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可燃性額定值單位制測試方法極限氧指數(shù)30 到 32%ASTM D2863
