It is also called additive and compounding agent. In industrial production, auxiliary chemicals are added to improve the production process, improve product quality and output, or endow products with a unique application performance. It is a major category of products in the fine chemical industry, widely used in plastics, rubber, synthetic fiber, coatings, printing and dyeing, paper making, leather, food, oil mining and other industrial fields. additive have a variety of varieties. They can be divided into organic and inorganic in terms of chemical structure, natural and synthetic in terms of source, low molecular and macromolecule in terms of molecular weight, synthesis and processing in terms of synthesis and processing of materials, and initiator, promoter, antiager, cross linking agent, plasticizer in terms of function. Some of them have multiple functions, and it is difficult to classify them completely in one way. It is generally classified according to its function and has strong practicality, which can be divided into synthetic, processing, thermal/mechanical performance, protective, etc.
