According to the requirements of conventional vulcanization processes such as compression vulcanization, hot air vulcanization, continuous steam vulcanization, or solution vulcanization, a vulcanizing agent with an appropriate decomposition temperature should be selected. In addition, sometimes a composite vulcanizing agent will have a better vulcanizing effect. The combination of peroxide desulfurizing agents with different decomposition temperatures can play a step start vulcanization effect, thereby achieving the comprehensive effect of avoiding scorch and rapid and complete vulcanization. For methyl vinyl silicone rubber, a combination of a peroxide curing agent and an addition reaction vulcanization catalyst platinum complex can achieve obvious effects such as improving mechanical strength, improving color and transparency.
