摘　　要：介绍了聚四氟乙烯(PTFE)的应用情况;阐述了PTFE的可熔融加工方法,包括柱塞冲压式挤出、可熔融加工的PTFE组合物、可熔性PTFE、超临界二氧化碳在PTFE挤出成型中的应用;分析了PTFE可熔融加工的难点;提出了PTFE可熔融加工的研究方向。The applications of polytetrafluoroethylene （PTFE） were discussed. The progress of research on meh-processable methods of PTFE was summarized, including ram-punch extrusion, the melt - processible PTFE compositions, PFA and the applications of extruding PTFE assisted by supercritical CO2. And the PTFE melt-processible difficulties were presented. The PTFE melt processing methods and research directions were stated.
