The filler is preferably a precious metal, especially silver, and its preferred form is as a coating on copper or glass. The element may be composed of a plurality of layers of knitted mesh embedded in the elastomer and the directions of extension of the loops in the layers are at angles to one another. The element is useful as a combination gasket and electromagnetic shield.Field of SearchKnitted, with particular or differential bond sites or intersectionsIncluding particulate material Free metal or mineral containing Including metal layer Including a second component containing structurally defined particles Glass or ceramic (i.e., fired or glazed clay, cement, etc.) (porcelain, quartz, etc.) As siloxane, silicone or silane Next to metal | |
