Sulfurized antioxidants and antioxidants are two common types of additives in the chemical industry. Although they are similar in some aspects, there are some obvious differences in the role and production process.

vulcanized antioxidants are mainly used in the rubber industry, and their function is to prevent the vulcanization reaction of rubber products during use, thereby extending their service life. It can effectively delay the aging speed of rubber products and maintain the stability of their mechanical and physical properties. Vulcanized antioxidants protect rubber products by inhibiting the oxidation process in the vulcanization reaction.

and antioxidant is a chemical additive, widely used in food, medicine, cosmetics and other industries. Its function is to delay the oxidation reaction of the product, prevent it from spoilage and deterioration, and maintain the stability and quality of the product. Anti-aging agent can inhibit the growth of microorganisms in food, prevent food from becoming sour and breeding harmful substances. In cosmetics, anti-aging agents can delay its oxidation, yellowing and deterioration process, maintain its color and fragrance. In the production process of

, there are some differences between vulcanized antioxidants and antioxidants. Vulcanized antioxidants usually exist in the form of organic sulfur compounds, common vulcanized antioxidants are sulfur, mercaptan, etc. The antioxidant can be organic compounds of various chemical structures, such as styrene, salicylate, etc. In addition, the main production method of vulcanized antioxidants is chemical synthesis, while antioxidants can be obtained by natural extraction or chemical synthesis.

In summary, there are some obvious differences between vulcanized antioxidants and antioxidants in the role and production process. Vulcanized antioxidants are mainly used in the rubber industry to prevent vulcanization reaction and oxidation process and protect the performance of rubber products; while antioxidants are widely used in food, medicine, cosmetics and other industries to delay the oxidation reaction of products and maintain their quality. In addition, the chemical structure and production methods of the two are also different. Understanding these differences helps to correctly select and apply the corresponding products.
