摘要： The invention relates to fluoropolymer articles that have been irradiated with at least 5 Kilo Gray of radiation, where the resulting articles have low levels of leachable or extractable fluoride ion. The low fluoride ion migration from the irradiated article is due to the presence of low levels of metalic salts or oxides in the fluoropolymer composition. The invention is especially useful for fluoropolymer articles in which the fluorpolymer layer contacts a biological or pharmaceutical fluid, and that are subjected to sterilization by irradiation.

The hose may consist of a irradiation-grafted fluoropolymer inner layer and a polyolefin outer layer, or multilayer hose with either a central irradiation-grafted fluoropolymer layer and polyolefin inner and outer layers, or a polyolefin central layer and irradiation-grafted fluoropolymer inner and outer layers. The irradiation-grafted fluoropolymer layer may be replaced with a layer of a blend of a fluoropolymer, preferably PVDF, and of an irradiation-grafted fluoropolymer. It may also be covered with a fluoropolymer.

摘要： The invention relates to a foamed fluoropolymer, preferably a polyvinylidene fluoride (PVDF) structure, such as from Kynar® resins. The foamed structure is continuous self-supporting, sized, and has a dense skin. The foamed structure is manufactured in a process using foaming agents and nucleating agents. The structure is sized into a specific shape during the manufacturing process—requiring a good melt viscosity of the PVDF foam. In one process, a master batch containing the nucleating agent is used. The foamed article could be a sheet, film, profile, tube, pipe, article, rod foam-core structure, or other self-supporting shape. Foamed tubes, pipes, rods, sheets and conduit are especially useful. The foamed structure of the invention provides added value by being lighter weight, more flexible, and more impact resistant than a comparable non-foamed PVDF structure. It also has increased hysteresis, increased insulation properties, reduced dielectric constant, and increased compressibility.

摘要： The invention relates to compositions of polyvinylidene fluoride (PVDF) and its copolymers that have been modified with an onium salt. The PVDF compositions exhibit an increased melting point, a reduced heat distortion and piezo properties. The improved properties can be further enhanced through annealing, and/or the addition of nanoclays. Additionally, the combination of PVDF, nanoclays and annealing can also produce a PVDF with an increased melting point and piezoelectric properties.
