Abstract: A gasket device for shielding electromagnetic radiation is comprised of several alternating areas of two different elastomeric materials, one of which is conductive. The areas of conductive material are substantially thinner than the other areas and provide a conductive path from one side of the gasket to the other.

Abstract: A gasket shield for counteracting electromagnetic interference is provided with a thin, elastomeric outer layer encapsulating a thicker, elastomeric inner layer as a flexible gasket, the outer layer constituting a metal-filled-elastomer exhibiting high conductivity and excellent attenuation of electrical energy. The thin outer layer is deposited by coating from solution such as by slot-head coating, dip-coating, gravure roll coating, spray coating or knife coating. In this way a thinner and more uniform outer layer can be provided than is achievable by co-extrusion, thereby providing a greater consistency and reduced costs, as well as a greater degree of metal-filling per unit volume of rubber matrix.

Abstract: An improved gasket shielding against magnetic waves is provided in the form of an integral two-layer component including a support layer and a cover layer, the support layer being strong and having excellent physical properties, and the cover layer being filled with ferrite or magnetite or the like.
