The present invention relates to a flame retardant polymer composition comprising a crosslinkable terpolymer comprising ethylene monomer units, a silane group containing comonomer units and comonomer units comprising a polar group; a metal carbonate filler and a silicone fluid or gum; wherein the content of the comonomer units comprising a polar group is between 2 and 25 wt % of the terpolymer and the content of the silane group containing comonomer units is between 0.2 and 4 wt % of the terpolymer. The present invention is also directed to the process for the production of the polymer composition, to a cable and/or to an electrical device having a layer comprising said polymer composition, and uses thereof.
