摘要： 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. A process to produce such composite material is also described as well as an EMI shield article made from such composite material and the use of such composite material in an EMO shield article.
