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. 与典型值比较 - Upgrade to compare!单位: SI 总览材料状态已商用：当前有效资料 1Technical Datasheet (English)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高刚性共聚物抗溶剂性耐化学品性能，良好延高的拉伸率用途泵件外壳形式粉状加工方法滚塑成型物理性能额定值单位制测试方法密度 / 比重1.72g/cm³ASTM D792表观密度0.75g/cm³内部方法熔流率（熔体流动速率） (297°C/5.0 kg)20g/10 minASTM D3159吸水率 (24 hr)< 0.030%ASTM D570平均颗粒尺寸270µm热性能额定值单位制测试方法熔融温度253°CASTM D3418线形热膨胀系数 - 流动 (0 到 100°C)9.0E-5cm/cm/°CASTM D696最高使用温度 3150°C
