摘要:
The invention relates to a metal/plastic hybrid and to a shaped body produced therefrom. By combining metallic additives in plastic, it has been shown for the first time that specific volume resistances of less than 10−2 Ωcm can be realized while the compounds have, at the same time, a good processability during the injection molding process.
