It can be used as vulcanization accelerator for natural rubber and diolefin synthetic rubber, slightly inferior to tetramethylthiuram disulfide and tetraethylthiuram disulfide in terms of efficiency, but with longer scorch time. It can be used as accelerator and vulcanizing agent for sulfur-free or low sulfur vulcanization. It solves the scorching problem of rubber which is difficult to be solved by TMTD, has good compatibility with rubber, no frosting, small compression deformation, 0.1-4 parts.
