Products labeled PFA 350 and PFA 350 X are equivalent and all information in this document is applicable to both. Typical Application Applications for DuPont™ Teflon ® PFA 350 include extruded tubing for use in handling aggressive fluids at high pressures; chemical linings for pipes used in the chemical processing industry; film for high flex service; and traditional extruded, injection-molded, or blow-molded articles requiring the unique performance of Teflon ® . Description DuPont™ Teflon ® PFA 350 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of Teflon ® PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both Teflon ® PFA 340 and 345 (Teflon ® PFA 350 has a typical MIT folding endurance of 500,000*, compared to that of 15,000 and 50,000 for Teflon ® PFA 340 and 345 respectively). Teflon ® PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for Teflon ® PFA 350. Teflon ® PFA 350 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of Teflon ® PFA 350 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. Teflon ® PFA 350 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® PFA 350 resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and excellent weather resistance. In a flame situation, products of Teflon ® PFA 350 resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke. Teflon ® PFA 350 meets the requirements of ASTM D3307, Type III 总体材料状态 • 已商用：当前有效资料 1 • Technical Datasheet (English) UL 黄卡 2 • E54681-244681 搜索 UL 黄卡 • DuPont Fluoropolymers • Teflon® PFA 供货地区 • 北美洲 • 欧洲 • 拉丁美洲 • 亚太地区 • 低摩擦系数 • 良好的柔韧性 • 热稳定性，良好 • 高 ESCR（抗应力裂纹） • 流动性低 • 韧性良好性能特点 • 良好的电气性能 • 耐化学性良好 • 吸潮性差 • 良好的抗蠕变性 • 耐气候影响性能良好 • 烟释放，低 • 良好的熔体强度 • 耐热性，中等用途 • 薄膜 • 吹塑成型应用 • 衬里 • 管道形式 • 颗粒料加工方法 • 吹塑成型 • 树脂传递成型 • 注射成型 • 挤出 • 压缩模塑物理性能额定值单位制测试方法比重 2.15g/cm³ ASTM D792 熔流率 (372°C/5.0 kg) 2.0g/10 min ASTM D3307 ISO 12086 吸水率 (24 hr) < 0.030% ASTM D570 机械性能额定值单位制测试方法抗张强度 ASTM D3307 23°C 28.0MPa ISO 12086 250°C 14.0MPa Teflon® PFA 350 全氟烷氧基 DuPont Fluoropolymers 机械性能额定值单位制测试方法伸长率 ASTM D3307 断裂, 23°C 300% ISO 12086 断裂, 250°C 500% 弯曲模量 ASTM D790 23°C 625MPa ISO 178 250°C 69.0MPa 硬度额定值单位制测试方法硬度计硬度 (邵氏 D) 55 ASTM D2240 ISO 868 热性能额定值单位制测试方法熔融温度 305°C ASTM D4591 电气性能额定值单位制测试方法体积电阻率 1.0E+18ohm•cm ASTM D257 ISO 1325 介电强度 0.250 mm 4 80kV/mm ASTM D149 0.250 mm 80kV/mm IEC 60243-1 介电常数 (1 MHz) 2.03 ASTM D150 IEC 60250 耗散因数 (1 MHz) < 0.00020 ASTM D150 IEC 60250 可燃性额定值单位制测试方法 UL 阻燃等级 5 V-0 UL 94 极限氧指数 > 95% ASTM D2863 ISO 4589-2 补充信息额定值单位制测试方法 Critical Shear Rate (372°C) 12.0sec^-1 MIT Folding Endurance 6 (200.0 µm) 5.0E+5Cycles ASTM D2176 Weather and Chemical Resistance: Outstanding 东莞市双帮塑胶原料有限公司大量销售塑料PFA PFA 350因为塑料价格行情每天都有新的变化前天的报价不等于今天的报价。如果需要新的价格请电：13549213581，肖生。
