This application relates to compositions of cross-linking peroxides which have excellent storage stability, without exudation of peroxide taking place, which contain the organic peroxide in a high concentration, and which are easily blendable with a rubber to be cross-linked. The compositions are obtained by mixing a softening agent with a Brookfield viscosity of 10,000 poises or less at 60 °C with an organic peroxide, preferably in the presence of a filler, and optionally with further ingredients. |
