Nickel Graphite Conductive Fillers Assure Corrosion Resistance in Severe Environments

August 6, 2008 Interference Technology Products, Shielding, Technologies

E-Fill™ nickel graphite powder from Sulzer Metco is a conductive filler used in the formulation of raw material for EMI gaskets and seals. Ni graphite powders are polymer additives that are usually combined with silicone to form electrically conductive elastomers. These nickel graphite conductive fillers give EMI gaskets shielding capabilities comparable to that of silver conductive filler additives over a wide frequency range. The nickel graphite’s angular shape combined with a proprietary highly conductive hard nickel coating gives the gasket material the “bite” needed to ensure the best electrically conductive seal for enhancing EMI and RFI shielding. E-Fill™ nickel graphite fillers are aluminum compatible and offer enhanced galvanic corrosion resistance and stability in severe environments. Learn more about E-Fill at the Sulzer Metcowebsite.
