The invention relates to a black smoke composition and to polymeric compositions containing it, used as semiconductor compositions or as premixes. The carbon black composition according to the invention consists of carbon black 0.1 to 50% by weight of at least one binder containing polyhydric alcohol. The polymer composition according to the invention contains a polymeric component, carbon black and at least a release agent. The carbon black composition contains ethoxylated esters, polyethers, ethoxylated alcohols or non-ethoxylated esters, which are incorporated into the composition of fluffy carbon black, in a depeleting process, to obtain carbon black pellets, with resistance to crushing, content reduced dust and fluids, which give polymer systems improved mechanical and rheological properties. |
