Abstract
The disclosure provides a composition as well as a set of compositions and method for producing cellular or foamed or blown fluoropolymers such as perfluoropolymers and other thermoplastics articles allowing for the creation of a lower cost communications cable, conductor separator, conductor support-separator, jacketing, tape, wire insulation and in some cases a conduit tube as individual components or combined configurations that exhibit improved electrical, flammability and optical properties. Specifically, the foamable or blown fluoropolymer such as a perfluoropolymer cellular insulation composition comprises; talc and the selected fluoropolymer such as perfluoropolymers. Compounded pellets or products resulting in cellular or foamable products using these pellets has also been realized by providing the melt combination in the pellets of only talc and a perfluoropolymer.
