  • Composite material with EMI shielding properties and process to produce it
    Patent number: 11889671
    Abstract: The disclosure provides for a composite material suitable for use as EMI shielding material, remarkable in that it comprises a component A being a polymer resin being at least one amorphous polymer resin and/or at least one semi-crystalline polymer resin selected from polyethylene resin and/or polypropylene resin; from 15.0 to 60.0 wt. % of component B being at least one metal-coated particle based on the total weight of the composite material; and from 0.5 to 5.0 wt. % of component C being one or more dispersants based on the total weight of the composite material; wherein one or more dispersants are selected from fatty acids, fatty acid derivatives, ethylene bis stearamide, functionalized waxes, maleic anhydride-grafted polymers and any mixture thereof; wherein the blend of components A, B and C shows a density ranging from 0.8 to 2.0 g/cc.
