Abstract
Abstract Metallized moldings of polymer mixtures comprise a thermoplastic and a filler. The thermoplastic polymer has a melting point of more than 100 DEG C. and may be selected from the group consisting of fluoropolymers, polyamides, polycarbomates, polyesters, polyimides, liquid crystalline polymers, polymethyl methacrylates, polyphenylene oxides, polysulfones, polyurethanes and silicones. The filler may comprise oxidized polyarylene sulfide polyarylene sulfide, polyimide, aromatic polyester, or polyether ketone.
