ECTFE 2000

乙烯三氟氯乙烯共聚物 Ethylene-chlorotrifluoroethylene copolymer 此材料从低温到 330T的性能良好，其强度、耐磨性、抗蠕变性大大高于PTEE、FEP和PFA。它在室温和高温下耐大多数腐蚀性化学品和有机溶剂。它的介电常数（2.6）低，在很宽的温度和频率范围内性能稳定。ECTFE不着火，可防止火焰扩散，当暴露在火焰中时，将分解成硬质的碳。 [1] ECTFE可制成用于模塑和挤塑的粒料及用于旋转模塑、流化床涂饰、静电涂饰的粉状产品。可在传统挤塑设备用化学发泡法加工成泡沫状产品，待别适用于计算机用电线的领域。半成品有膜、板、管和单纤维。 Ausimont USA公司销售的ECTFE产品牌号为Halar。 在电线和电缆领域，最重要的应用是用于增压电缆、公共交通车用电缆。火警电缆、阳极保护电缆。注塑产品有塔填料、问和泵零件、接插件、电线接线柱、过滤机壳。ECTFE管的应用有光导纤维的套管、非支撑管、钢管和增强塑料管的内衬。 ECTFE涂料和内村可防止金属被环境侵蚀。膜的应用有理电池和隔离方面的应用。单纤维的应用有消油雾器、编织套管、过滤织物。宽幅（48in）以玻璃纤维作背村的ECTFE片材，可用作耐化学品和强度要求高的槽罐的内衬。 Overview of materials for Fluorocarbon ETFE/ECTFE, Molded/Extruded Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "Fluorocarbon ETFE/ECTFE, Molded/Extruded".
