| abstract |
A thermoplastic fluoropolymer which has improved tensile strength, yield strength, and cut- through resistance at elevated temperature. In a preferred embodiment, the fluoropolymer is an ionomer which comprises at least 40 mole percent perfluorinated repeat units and at least 0.4 mole percent repeat units which contain at least one anion of a salt group. Fluoropolymers of the invention are particularly useful for airframe wire. |
