Abstract
The present invention relates to a vulcanizable elastomeric composition comprising a secondary accelerator that may be used in combination with sulphenamide alone, completely avoiding the use of a guanidine. Moreover, said accelerator promotes dispersion of the silica in the compound and migrates with difficulty in the elastomeric composition itself. The invention also relates to the use of a vulcanization accelerator for said elastomeric composition, to the associated vulcanization process and to a tyre comprising same.
