Carbon black compositions comprising ethoxylated esters or polyethers and carbon black. The compositions may be produced by incorporating ethoxylated esters or polyethers onto fluffy carbon black in a pelletizing process to produce free flowing, low dust, attrition resistant carbon black pellets which are easily dispersible in most polymeric systems and impart to polymer compositions enhanced rheological and mechanical properties. The polymeric compositions have particular utility as semiconductive compositions or masterbatch compositions.
Compositions de noir de carbone comprenant des esters ou des polyéthers éthoxylés et du noir de carbone. On peut préparer ces compositions par incorporation d'esters ou de polyéthers éthoxylés dans le noir de carbone pelucheux dans un procédé de mise en granules permettant de fabriquer des granules de noir de carbone coulants, produisant peu de poussière et résistant à l'usure, qui se dispersent facilement dans la plupart des systèmes polymères et améliorent les propriétés rhéologiques et mécaniques des compositions polymères. Ces compositions polymères sont particulièrement utiles en tant que compositions de semi-conducteurs ou de mélanges maîtres.
