MELT PROCESSIBLE FLUOROPOLYMER COMPOSITION

摘要

Blends of 3 to 97 parts by weight of tetrafluoroethylene/hexafluoropropylene copolymer containing 3 to 9 wt% hexafluoropropylene and 0 to 4 wt% of tetrafluoroethylene/perfluoro(ethyl vinyl ether) or tetrafluoroethylene/perfluoro(methyl vinyl ether), with 97 to 3 parts by weight tetrafluoroethylene/perfluoro(ethyl vinyl ether) or tetrafluoroethylene/perfluoro(methyl vinyl ether), which co-crystallize are found to have improved melt strength and improved mechanical properties, and a higher service temperature than the tetrafluoroethylene/hexafluoropropylene copolymer.
