The invention relates to a vulcanisation accelerator combination and their use for a process for vulcanising natural and/or synthetic rubber made from halogen-free dienes. As vulcanisation accelerators triazines substituted in the 2, 4 and 6 positions in combination with at least one thiazole accelerator and optionally at least one thiuram accelerator are used. This accelerator combination obviate the disadvantage of the long cure time when using the triazine accelerator alone without loss of the advantage of the high moduli.
