MELT PROCESSIBLE FLUOROPOLYMER COMPOSITION

摘要

A melt processible fluoropolymer composition comprising a copolymer of tetrafluoroethylene with a perfluoro(alkyl vinyl ether), which copolymer is a mixture of a first fluorocarbon resin copolymer in which the alkyl group of the perfluoro(alkyl vinyl ether) has at least 3 carbons, and a second fluorocarbon resin copolymer in which the alkyl group of the perfluoro(alkyl vinyl ether) has 1 and/or 2 carbons, and the components of the blend are miscible in the amorphous regions and sometimes in the crystalling regions.
