Tefzel? 2195Generic Name: 乙烯四氟乙烯共聚物 (ETFE) - 提供方: The Chemours CompanyTefzel ? ETFE HT-2195 is a premium-grade fluoroplastic resin designed for use in rotational molding. To be effective as a rotational molding resin, Tefzel ? ETFEHT-2195 is a free-flowing powder with controlled particle size, shape, and size distribution.The properties of Tefzel ? 2195 in molded form are similar to other grades of Tefzel ? fluoropolymer resin.Rotational molding is a favored process for making hollow parts (particularly large parts) or for parts with complex geometries. Depending on part design and processing conditions, Tefzel ? 2195 can also be used to rotoline items, whereby the Tefzel? binds to the inner surface of the part to form a lining.Properly processed rotational moldings made from Tefzel ? 2195 provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 150°C (302°F), useful properties at -100°C (-148°F), and chemical inertness to most industrial chemicals and solvents. Molded products have excellent stiffness and high ultimate elongation.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 ? 2195 is ideal for many end products for fluid handling in the chemical processing industries, including pump housings, vessels, columns, elbows, tees, and pipe sections with unusual shapes. In addition, any hollow structure with internal contours that permits uniform coating by powder flow is a candidate for lining, provided it can withstand high temperatures. 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Excellent Weather Resistance高剛性共聚物抗溶劑性耐化學(xué)品性能，良好延高的拉伸率用途泵件外殼形式粉狀加工方法滾塑成型物理性能額定值單位制測(cè)試方法密度 / 比重1.72g/cm3ASTM D792表觀(guān)密度0.75g/cm3內(nèi)部方法熔流率（熔體流動(dòng)速率） (297°C/5.0 kg)20g/10 minASTM D3159吸水率 (24 hr)< 0.030%ASTM D570平均顆粒尺寸270μm熱性能額定值單位制測(cè)試方法熔融溫度253°CASTM D3418線(xiàn)形熱膨脹系數(shù) - 流動(dòng) (0 到 100°C)9.0E-5cm/cm/°CASTM D696最高使用溫度 3150°C
