可发泡含氟聚合物组合物
摘要：
本发明提供了一种可发泡含氟聚合物组合物，所述组合物含有泡孔成核剂，其中所述含氟聚合物包含可熔融制造的四氟乙烯/六氟丙烯共聚物和四氟乙烯/全氟(烷基乙烯基醚)共聚物，其中所述烷基含有1至4个碳原子，其中所述四氟乙烯/全氟(烷基乙烯基醚)共聚物的熔融温度比所述四氟乙烯/六氟丙烯共聚物的熔融温度高不超过35℃，和/或其中所述四氟乙烯/六氟丙烯共聚物和所述四氟乙烯/全氟(烷基乙烯基醚)共聚物各自具有在1至40g/10min范围内的熔体流动速率(MFR)，并且所述共聚物中的一种的MFR为所述共聚物中的另一种的至少两倍。
摘要（英）：

A foamable fluoropolymer composition containing foam cell nucleating agent is provided, wherein the fluoropolymer comprises melt-fabricable tetrafluoroethylene-/ hexafluoropropylene copolymer and tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, wherein the alkyl contains 1 to 4 carbon atoms, wherein the melting temperature of said tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer is no more than 35 DEG C greater than the melting temperature of said tetrafluoroethylene/hexafluoropropylene copolymer, and/or wherein said tetrafluoroethylene/hexafluoropropylene copolymer and said tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer each have a melt flow rate (MFR) within the range of 1 to 40 g/10 min and the MFR of one of said copolymers is at least twice that of the other of said copolymers.
