In the synthesis of silicone rubber, various catalysts and the adjustment of silica and white carbon are always indispensable. The same semi-finished raw materials are indispensable for the addition of various color rubbers and vulcanizing agents during the molding and vulcanization of silicone products. Therefore, Different types of vulcanizing agents can play different roles and effects. The role of the vulcanizing agent is a very important auxiliary material in silicone products. If the vulcanizing agent is used well, the product will be icing on the cake; if it is not used properly, there will be major problems! In the future, for the silicone products required by medical food grade, platinum vulcanizing agent will replace peroxide, which is also the general trend of the future excipient market.

Generally, the common vulcanizing agent is mainly peroxide, which is used for the production and vulcanization of ordinary molded silicone products. Used for industrial accessories, electronic silicone parts, silicone seals, etc. occupy the majority, belonging to the national standard model products!

The common odorless vulcanizing agent in the market is the common mild-flavored peroxide. It is mainly used for molding and molding of silicone rubber products that contact human skin, such as children's toys, silicone daily necessities, silicone decorations, etc. It is suitable for colored parts and transparent and white products. It can be slightly odorous after one-time vulcanization, and the second-stage vulcanization is better. (180-200℃ for 4-8 hours), the product is flammable. When mixing, add silica gel vulcanizing agent and the same proportion of strengthening agent to mix well, and then quickly add the remaining raw materials to avoid fire. Due to the defects after secondary vulcanization, it has a sour taste, is flammable and volatile, and is currently not suitable for children's toys, tableware, food contact silicone products, and a substitute for platinum vulcanizing agent. Certification.

Transparent paste, odorless anti-yellowing vulcanizing agent, is a mixture of peroxide and raw rubber carrier. It is also used in the molding and vulcanization process of silicone products. It is used for long-term use in high-quality products. It is used for transparent, translucent and white, translucent Color and other products prevent yellowing. For transparent or white parts, it can ensure that the product does not turn yellow within the high temperature multiple vulcanization (or the secondary vulcanization is baked within 200 ℃ for about 4 hours). It is suitable for colored parts to resist yellowing. It is guaranteed that the colored parts will not change color after vulcanization for many times and will not change color after long-term use!
