EMI Shielding Silicone

Gallery focus image

Our EMI-shielded products range from electrically conductive elastomers in molded, extruded, die-cut forms. EMI shielding silicones are elastomeric compounds infused with conductive particles such as nickel-graphite, silver-aluminum, or silver-coated copper. This composition enables the silicone to conduct electricity, allowing it to reflect or absorb electromagnetic waves that could otherwise disrupt electronic circuits.
