Generally, DTDM/TMTD is used in combination, or sulfenamide or thiazole accelerator is used to adjust the scorch period and vulcanization rate.

The vulcanizing agent DTDM can adapt to the vulcanization temperature of 140 °C-200 °C, and the scorch safety is good. After reaching the normal vulcanization temperature, the vulcanization rate is accelerated, and the vulcanization property is ideal. DTDM does not spray, does not pollute, and is easy to disperse in the rubber compound, and has good processing performance. DTDM releases high-efficiency vulcanization rubber with high-efficiency vulcanization properties, which can significantly improve the resistance of vulcanizates. DTDM can decompose morpholine free radicals with amine antioxidants in the rubber compound, which can make the vulcanized rubber have excellent heat and oxidation resistance. DTDM has excellent thermal properties and is ideal for the manufacture of dynamic heat-resistant rubber products. It can reduce the heat-generating NR and SNR and is an ideal rubber vulcanizing agent.

With the increase of people's environmental protection concepts and health concerns, it has been found that the vulcanizing agents DTDM and thiuram products will cleave at the vulcanization temperature to release secondary amino-based molecular fragments, which can be combined with the nitroso donor to produce carcinogens. Nitrosamines, so the production and application of vulcanizing agents DTDM and thiurams are subject to the limits and warnings of European and American countries and environmental regulations. At present, the new vulcanizing agent DTDC (N, N-di(ε-caprolactam) disulfide) has attracted international attention due to the fact that it does not produce nitrosamines during vulcanization. It is considered to be a vulcanizing agent DTDM and disulfide or hexasulfurate. The best alternative to M, replacing the vulcanizing agent DTDM with the same amount, without changing the formulation and process of the compound
