Electroseal™ Conductive Elastomer Extrusions Laird Performance Materials Electroseal™ Conductive Elastomer Extrusions provide environmental sealing and excellent mechanical and electromagnetic shielding properties. The shielding system consists of a conductive gasket sandwiched between a metal housing and lid. The primary function of these gaskets is to provide sufficient electrical conductivity across the enclosure/gasket/lid junction to meet grounding and EMI shielding requirements. The conductive elastomer extrusions from Laird are ideal for applications that demand both environmental sealing and EMI shielding and can be used in a wide range of operating temperatures. The compounds can be supplied in molded or extruded shapes, sheet stock, custom extruded, or die-cut shapes to meet a wide variety of military and commercial applications.
