This composition has potential applications in the rubber-processing industry for obtaining rubber compositions, as well as for moulding the latter by the pressure casting method. It has similar rheological and retained physical characteristics, as well as mechanical characteristics. The amount of high-molecular additive used contributes to the simplification of the process conditions under which the composition is prepared. The elastomer composition contains 0.20 - 2.50 parts by weight of high-molecular additive and silicon rubber with 100 parts per weight of the rubber. The elastomer represents natural or butadiene nitrile rubber with the other components contained in the following weight parts: zinc oxide 1-5, stearine 0.1-1.5, dyoctil phthalate 2-10, colophene 1-10, cyclohexyl-phenyl-p-phenyl diamine 1-3, furnace black 30-100, sulphur 0.5-1.5, thiuram 1-2.5, cyclohexyl-2-benzthiazolil sulphenamide 1-2.5, di-/2-benzthiazolil/-disulphide 1-2.5, paraffin 2-10, kaolin 10-40, Vulcasil 20-60, and diphenyl guanidine 0.5-2.
