Antioxidants and heat resistants are two important concepts in the field of chemistry, and they play an indispensable role in different application scenarios. This article will detail the differences between antioxidants and heat-resistant agents and their respective applications. Antioxidants

refer to chemicals that prevent oxidation reactions and can help reduce or delay the oxidation process. Oxidation reaction refers to the chemical reaction between substances and oxygen, which will lead to the deterioration, corrosion and aging of substances. Common application fields of antioxidants include food industry, cosmetics, plastic processing, etc. By adding antioxidants, vitamins and nutrients in food can be effectively protected to prevent food deterioration; in cosmetics, antioxidants can enhance the stability of cosmetics and extend the service life; in the process of plastic processing, antioxidants can reduce plastic aging and yellowing. The main function of antioxidants is to inhibit or neutralize the production of oxygen free radicals, so as to prevent the oxidation reaction.

anti-heat agent refers to a chemical substance that can prevent or slow down the deterioration of the thermal properties of the substance. At high temperature, many substances are easy to melt, deform or deteriorate, thus affecting their normal use function. The heat resistance agent can stabilize the structure and performance of the material in a high temperature environment and prolong its service life. Common application areas for heat resistants include plastic processing, rubber products, coatings, etc. By adding heat resistant agent, can improve the high temperature resistance of plastic, reduce plastic deformation at high temperature; in rubber products, heat resistant agent can improve the anti-aging properties of rubber, prolong the service life; in the coating, heat resistant agent can improve the high temperature resistance and oxidation resistance of the coating.

Although antioxidants and anti-heat agents are different in the mechanism of action, they also have certain overlap in some applications. For example, in rubber products and plastic processing, heat resistance and antioxidants are often added at the same time to achieve comprehensive performance improvement. In addition, the anti-heat agent and antioxidant can also cooperate with other additives to play a better role together. Therefore, in practical applications, understanding the difference between antioxidants and anti-heat agents and their interactions can better select the appropriate dosage form and improve the quality and performance of the product.

In conclusion, antioxidants and heat resistants play an important role in the field of chemistry. Antioxidants are mainly used to prevent oxidation reactions, and heat-resistant agents are mainly used to prevent substances from deteriorating and failing at high temperatures. They have their own unique application value in different application fields. Understanding their differences and applications can help us better understand and apply these two dosage forms and play a better role in product development and production.
