Silicone rubber product is now more and more popular, especially in Europe and the United States and the Japanese market is more common. Especially the silicone ice tray, silicone table mat  are more popular. The silicone rubber secondary sulfide have any impact on product quality? Factors in vulcanization of rubber, silicone rubber using peroxide vulcanizing, peroxide decomposition result in a polymer reaction after the production of low molecular compounds such as benzene and benzoic acid, etc.) exists in will affect the mechanical properties of rubber, Silicone rubber after the first hot forming, the crosslink density is not enough, must be secondary sulfide can increase the density of silicone rubber, stretching intensity.
