The invention relates to the use of inorganic fluoride compounds as fillers for use in fluoropolymers, such as polyvinylidene fluoride (PVDF) and its copolymers. The filled fluoropolymer is especially useful in articles where limited combustion and low smoke are required—such as in cables and conduits. The invention also relates to a filled PVDF as a means of lowering costs and improving performance properties in any application.
