Classification and function of chemical additives

Chemical additives are a type of additives widely used in the chemical production process to improve the processing performance and quality of chemical products. According to different uses, chemical additives can be divided into plasticizers, vulcanizers, antioxidants and other types.

Plasticizer: Enhance flexibility and processing performance

Plasticizers are additives used to improve the processability and softness of chemical products. By adding plasticizers, the ductility and cold resistance of products can be enhanced. Common plasticizers include paraffin, esters and fatty acid esters. Different plasticizers can be selected to achieve the desired effect according to different types of chemical products and specific requirements.

Vulcanizing agent: improve product strength and elasticity

Vulcanizing agents are indispensable in chemical products. They can promote the cross-linking reaction between chemical product molecules and improve the strength and elasticity of products during processing and use. Common vulcanizing agents include diethyl sulfate, lead sulfide, peroxide, etc. Different vulcanizing agents are suitable for different types of chemical products and vulcanization systems.

Anti-aging agent: prolong product life

Antioxidants are another important type of chemical additives. Their main function is to slow down the aging of products and improve weather resistance and heat resistance. Common antioxidants include aromatic phenols, anilines and phenolphthalein. By adding an appropriate amount of antioxidants, the aging and cracking of chemical products can be effectively avoided, thereby extending their service life.

Other important additives

In addition to plasticizers, vulcanizers and antioxidants, various other additives are used in chemical production, such as processing aids and fillers. Processing aids can improve the fluidity and processing properties of chemical products, making them easier to form; fillers can increase the strength, hardness and wear resistance of products, thereby improving product quality and performance.

The importance of additives in chemical production

In general, chemical additives play an irreplaceable role in modern chemical production. By rationally selecting and using additives, the processing performance and quality of products can be significantly improved, production efficiency can be increased, and production costs can be reduced. Therefore, in the chemical production process, optimizing the additive formula is the key to improving product quality and meeting market demand. Efficient use of chemical additives will help chemical companies maintain their competitive advantage in the fierce market competition and achieve sustainable development.
