Abstract

See full text

Perfluoropolymer composites are provided which are obtained by dispersing layered-silicates having properties of swelling or cleaving in dispersion media in perfluoropolymers and having the ratio of the viscosity, V0.1, at 0.1 rad/sec by a parallel plate mode of a dynamic rheometer to the viscosity, V1, measured at 1 rad/sec is 1.5 or greater, viscosity being measured at 340° C. A method for making the perfluoropolymer composites is provided, and molded articles therefrom. And additionally, perfluoropolymer composites, where layered-silicates having properties of swelling or cleaving in dispersion media are dispersed in perfluoropolymers, with the storage elasticity of 2 times or higher than that of fluoropolymers, at temperatures greater than the glass transition temperature of perfluoropolymers.
