Foamable Fluoropolymer Composition |
摘要 |
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° 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. |
