Thiuram rubber accelerators are acidic and belong to super speed accelerators, including thiuram monosulfide, thiuram disulfide and thiuram polysulfide. Thiuram disulfide can be used for sulfur-free vulcanization with a vulcanizing agent. As an accelerator, it is generally used as a second accelerator, together with thiazole and sulfenamide accelerators to increase the vulcanization rate. When used in combination with sulfenamide accelerators, it can delay the time when the rubber compound starts to react, and the reaction can proceed very quickly after the vulcanization starts, and the vulcanization degree of the vulcanizate is also relatively high. This production system is particularly important in low-sulfur vulcanization.

  The physical and mechanical properties and aging resistance of the vulcanized Chemicalbook adhesive with thiuram accelerator are affected by the ratio of accelerator and sulfur. Generally speaking, when the amount of sulfur is normal, the tensile strength of the vulcanizate is high, and other physical and mechanical properties are also better; when the amount of sulfur is low and the amount of accelerator is large, the heat aging resistance of the vulcanizate can be improved. The most commonly used variety of thiuram accelerators is tetramethylthiuram disulfide, and the trade name is accelerator TMTD, abbreviated as accelerator TT. It can be used as both an accelerator and a vulcanizing agent. When used as an accelerator, the dosage is generally 0.2 to 0.3 parts.
