Conductive rubber, also known as conductive elastomer, is made from (silicone) rubber with fillers such as pure silver, silver-coated copper, aluminum, nickel, glass, or graphite. It offers ideal shielding and can also be used for environmental sealing.

Conductive rubber can be processed by molding or extrusion: molded rubber can be made into various thicknesses, shapes, and die-cut gaskets, while extruded rubber can be produced in standard cross-sections like rectangles, circles, 'D', 'U', 'P' shapes, and custom profiles.
