Abstract:
A melt processible fluoropolymer composition having a single crystallization temperature and a single melting point, as measured with a differential scanning calorimeter, said composition comprising:(A) about 3 to about 97 parts by weight of a tetrafluoroethylene-hexafluoropropylene copolymer comprising about 3 to about 9 wt % hexafluoropropylene, and 0 to about 4 wt % of a third monomer that is at least one additional monomer selected from the group consisting of perfluoro(propyl vinyl ether), perfluoro(ethyl vinyl ether), and perfluoro(methyl vinyl ether), and about 89 to about 97 wt % tetrafluoroethylene; and (B) about 97 to about 3 parts by weight of a copolymer comprised of about 80 to about 99 wt % tetrafluoroethylene with about 1 to about 20 wt % of one or more comonomers selected from the group consisting of perfluoro(ethyl vinyl ether) and perfluoro(methyl vinyl ether).
