Foamed insulation of Teflon ® fluoropolymer foam resin FFR 880 provides high-speed data transmissions with minimal distortion and exceptional signal return loss and attenuation performance in ultra-thin wire and cable applications. In addition, the resin's high thermal stability and melt flow rate (nominal MFR of 42) allow for high processing speeds and excellent heat resistance. Teflon ® fluoropolymer foam resin FFR 880 offers cable designers opportunities for miniaturization and weight savings or the use of larger conductors to construct low-loss cables without the need for increased dielectric dimensions. Supplied as white pellets, Teflon ® fluoropolymer foam resin FFR 880 is used in a gas injected foam extrusion process to produce foamed dielectric insulation. The fluoropolymer resin is compounded with a proprietary nucleating package, which when combined with nitrogen gas injection, forms uniform foam cells in the insulation. In micro coaxial cables using Teflon ® fluoropolymer foam resin FFR 880, a typical cable core would have conductor sizes of 26 AWG or smaller, wall thickness of 0.002 in. or greater, with void content up to 55%. These voids are closed cell in nature and range from 0.0002 in. (0.006mm) to 0.0013 in. (0.033 mm) in diameter. Achievable cell size and void content will vary based on wall thickness and processing conditions. 总体材料状态 • 已商用：当前有效资料 1 • Technical Datasheet (English) 搜索 UL 黄卡 • DuPont Fluoropolymers 供货地区 • 北美洲 • 欧洲 • 拉丁美洲 • 亚太地区添加剂 • 成核剂性能特点 • 可发泡性能 • 耐热性，高 • 有核 • 流动性高 • 热稳定性，良好用途 • 电线电缆应用 • 绝缘材料 • 泡沫外观 • 白色形式 • 颗粒料加工方法 • 发泡挤出成型 • 挤出物理性能额定值单位制测试方法比重 2.14g/cm³ ASTM D792 熔流率 42g/10 min ASTM D3307 热性能额定值单位制测试方法熔融峰值温度 304°C ASTM D3307 电气性能额定值单位制测试方法介电常数 1 MHz 2.03 ASTM D150 1.00 GHz 2.03 ASTM D2520 耗散因数 1 MHz 0.00010 ASTM D150 1.00 GHz 0.00040 ASTM D2520
