Carbodiimide, also known as Carbodiimide, refers to a class of compounds containing the functional group -N=C=N- in the molecule. Carbodiimide is a commonly used anti-hydrolysis agent. According to the different components of carbodiimide anti-hydrolysis agents, it can be divided into monomeric carbodiimide anti-hydrolysis agents and polymeric carbodiimide anti-hydrolysis agents. .

Among them, the monomeric carbodiimide anti-hydrolysis agent molecule contains only one functional group and is a bright yellow to brown liquid or crystalline solid at room temperature. It is soluble in organic solvents, such as acetone, chlorobenzene, dichloromethane, etc., and is insoluble in water. The advantage of monomeric carbodiimide hydrolyzing agent is that it has high activity and reacts quickly and efficiently with carboxylic acid.

The polymeric carbodiimide anti-hydrolysis agent molecule contains only two or more functional groups and is a yellow to brown flaky powder at room temperature. The advantage is that it is not easy to volatilize and extract, has low toxicity, and can play a role that is difficult to achieve with single carbodiimide. It has the function of “replantation” of broken polymer chains, so most of the industrialized varieties of anti-hydrolysis agents at home and abroad are polymeric carbodiimides.

Anti-hydrolysis agents can improve the stability and persistence of chemical substances in water and are widely used in chemical industry, pesticides and other fields, thereby improving their effectiveness and service life. Industrial Research Center released “China’s Carbonization in 2023-2028” The “In-depth Market Research and Development Prospects Forecast Report on the Diimine Anti-Hydrolysis Agent Industry” shows that with the continued development of the downstream industry, the demand for anti-hydrolysis agent products in various application fields of anti-hydrolysis agents has increased. Therefore, China The market size of the anti-hydrolysis agent industry continues to rise. Among them, carbodiimide anti-hydrolysis agents are the variety with recognized effects and the widest range of applications, accounting for more than 80% of China’s total demand for anti-hydrolysis agents.

The research and industrialization development of anti-hydrolysis agents in China is relatively late. Domestic scientific research institutions and related enterprises in China have conducted a lot of research on the preparation methods and applications of anti-hydrolysis agents such as carbodiimide anti-hydrolysis agents, which has promoted the development of anti-hydrolysis agents in China. development of the pharmaceutical industry.

However, at present, there are still very few domestic anti-hydrolysis agent manufacturers in China. Only a few companies such as Shanghai Langyi Functional Materials Co., Ltd. and Suzhou Keshengtong New Material Technology Co., Ltd. have large-scale production capabilities. Shanghai Laian Industrial Co., Ltd. Some companies still mainly act as agents for imported products.

In the next few years, with the rapid recovery of China’s macro-economy, industrial upgrading and structural adjustment, terminal application fields such as TPU, PU, PET, and PBT may continue to maintain stable development. The development of the above-mentioned industries will bring about carbodiimide and other resistant chemicals. Growth in consumer demand for hydrolyzants. In addition, as the technical level and production process of domestic anti-hydrolysis agent companies improve, the product types and application fields of anti-hydrolysis agents will be expanded, thereby promoting the growth of domestic demand for anti-hydrolysis agents.

However, the number of manufacturing companies will not increase significantly in the short term, and the market will still present a pattern of competition between domestic products and imported products. At the same time, with the growth of local companies such as Shanghai Langyi Functional Materials Co., Ltd. and Suzhou Keshengtong New Material Technology Co., Ltd. With the growth, the quality, performance and variety of domestic anti-hydrolysis agent products will be improved, and localization will be further improved.
