　　Silicone products will turn yellow after being used for a long time, such as some silicone industrial accessories; silicone kitchen utensils, etc., all have similar situations. In particular, products with darker colors and products with high transparency are most likely to occur. This yellow substance affects the appearance of the product, and the appearance requirements of some silicone gifts or silicone accessories cannot be guaranteed.

　　Professionals all know that silicone products are actually vulcanization reaction products, a process of chemical reaction. Silica gel itself is a colorless and translucent substance. After adding vulcanizing agent, it can be mixed with silica gel. Mixed rubber is silica gel that has been added with a vulcanizing agent. It will also undergo oxidation-reduction reaction when exposed for a long time. Therefore, generally, mixed rubber is used immediately after training. When mixing silica gel, a substance called a vulcanizing agent needs to be added. With this vulcanizing agent substance, the product will be rapidly formed. The main factor for the yellowing of silicone products is this vulcanizing agent, but not all vulcanizing agents will cause yellowing or deterioration of silicone products.
