FIELD: chemistry.

SUBSTANCE: invention relates to rubber compounds for the manufacture of vulcanisates, to a method for the manufacture and vulcanisation of said rubber compounds, to rubber articles containing vulcanisates, and to vehicles comprising rubber articles. Rubber mixture comprises at least one non-polar rubber selected from the group consisting of natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), isoprene rubber (IR), isoprene-styrene rubber (SIBR), butyl rubber (IIR), epoxidised natural rubber (ENR) and ethylene-propylene-dien-rubber (EPDM), as well as at least one carbon black, at least one cross-linking agent and at least one short-chain alkyl ester of glycerol of the formula given.

EFFECT: technical result is obtaining rubber compounds having improved processing properties, with the use of which vulcanisates with high values of hardness and tensile elongation are obtained.
