The invention relates to a voltage-limiting composition (1) or varistor composition, having a polymer matrix (2) and a particulate filler (4) containing a partially conductive material (5), wherein the partially conductive material (5) is applied to an electrically non-conductive carrier material (6), and wherein the carrier material (6) has a lower density than the partially conductive material (5). A settling rate of the filler in the polymer matrix is reduced as a result. The voltage-limiting composition can therefore also be used as a lacquer or for prepreg materials. The invention also relates to a body which acts as a varistor and has a composition of this kind, and to a method for producing a composition of this kind, which method comprises annealing. The invention can be used particularly advantageously for surge arresters with a varistor property, in particular in medium-voltage systems, low-voltage systems, cable connections and cable fasteners.
