1. Composite material suitable for use as EMI shielding material, characterized 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 22.0 to 50.0 wt. % of component B being at least one metal-coated particle based on the total weight of the composite material, wherein the at least one metal-coated particle of component B is metal-coated fibres with an average length of at least 150 μm, and wherein component B has a density of less than 4.0 g/cc; and
from 1.0 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 has a density ranging from 0.8 to 2.0 g/cc as determined by ISO 1183.
