摘　　要：乙烯和四氟乙烯共聚物(ETFE)是乙烯和四氟乙烯交替共聚合成的氟树脂,其不仅具有传统PTFE(聚四氟乙烯)的耐热、耐化学性、电绝缘性,而且其密度、耐辐射和机械性能有了很大程度的改善,拉伸强度可达到50 MPa,接近PTFE的2倍,被称为最强韧的氟塑料。同时它能够熔融加工,即可采用常规的热塑性树脂加工方法加工成型。它在电线电缆、防腐涂层等领域有着广泛的应用。Tetrafluoroethylene / ethylene copolymer（ ETFE） is alternating copolymer resin,which not only have traditional heat resistance,chemical resistance,electrical insulation compared with PTFE,also its gravity,resistance to radiation and mechanical performance has been significantly improved. Its tensile strength have been up to 50 MPa,nearly 2 times of PTFE,known as the most resilient fluorine plastics. Meantime it can be melting processed,using conventional thermoplastic molding methods. The copolymer have wide application for wire and cable,anticorrosion coatings and other fields.
