This is a yellow powder with a relative density of 1.37-1.40, non-toxic and odorless. Activity is about 10% lower than TMTD, vulcanized rubber fixed extension strength is also slightly lower, the critical temperature of vulcanization is 121 degrees Celsius, the after-effects than the disulfide of the autumn Rum accelerator are large, anti-scorch performance is excellent.
