Abstract
Described herein are solid and foamable fluoropolymer alloy compositions and foamed articles using said foamable fluoropolymer alloy compositions. The foamable fluoropolymer alloy compositions can comprise a fluoropolymer, and a plastic polymer mixed with said fluoropolymer, wherein said plastic polymer is miscible with said fluoropolymer. The fluoropolymer alloy composition may further comprise a foaming agent. By way of example, the foaming agent can be talc or a talc derivative, or a mixture of talc (or talc derivative) with a citrate compound, such as a citrate salt. One or more additives are added to render the compositions flame retardant and/or smoke suppressant.
