Abstract

Elektromagnetische Abschirmung mit einer mindestens zwei­ lagigen elektromagnetischen Abschirmung, deren eine Lage durch einen elektrischen Leiter wie einen Metallgeflecht­ schirm (C;D) gebildet ist und deren zweite Lage durch eine flexible, elektrisch nicht-leitende, mit nicht-­ magnetischen Metallteilchen dotierte Kunststoffschicht (D) gebildet ist. Electromagnetic shielding with at least two layered electromagnetic shielding, one layer of which through an electrical conductor like a metal braid screen (C; D) is formed and the second layer by a flexible, electrically non-conductive, with non- magnetic metal particles doped plastic layer (D) is formed.
