The invention relates to a conductive article such as a pipe or a container, wherein the article is made from a composite material comprising from 50 to 99 wt % of a first polyethylene resin having an HLMI ranging from 1 to 50 g/10 min, a melt index MI2 of at most 0.45 g/10 min, and a density ranging from 0.920 g/cm3 to 0.980 g/cm3; from 0.2 to 10 wt % of carbon particles selected from nanographene, carbon nanotubes (CNT) or any combination thereof; and from 0.01 to 5.0 wt % of one or more processing aids. The conductive article has a surface resistivity of at most 1.106 ohm/sq as determined according to silver ink method. The invention also relates to a process to produce such conductive article.
