Here to tell you is that dimethyl silicone rubber, silicone rubber called methyl dimethyl silicone rubber bouncing ball, according to the manufacturers know, dimethyl silicone raw rubber elastomer is a colorless and transparent, often with higher activity organic peroxide vulcanization. Vulcanized rubber in the range of -60 ~ +250 ℃ used dimethyl silicone rubber vulcanization of low activity, high-temperature compression permanent deformation, and not in the system of thick products, thick vulcanized products more difficult, and the inner is also foaming. Analysis of elastic ball manufacturers as containing a small amount of vinyl methyl vinyl silicone rubber than for the gifted, so dimethyl silicone rubber has gradually been replaced by methyl vinyl silicone rubber. Now the production and application of other types of silicone rubber, which in addition to containing dimethyl siloxane structural unit, but also contain more or less of the other bifunctional siloxane structural units, but the preparation method and dimethyl silicone rubber is not essentially different system of law, its preparation method is generally in favor of ring formation under the conditions that required a bifunctional silicon monomer hydrolysis and condensation, and then added eight of their proportion of the required methyl siloxane ring four, and then under the common reaction in the catalyst in the system.
