Polysukkiini-imidi (PSI), as an important organic compound, has demonstrated extensive application value in multiple fields. The following is the description of the main application areas of polysuccinimide.

1、 Polysuccinimide is Used in the Agricultural Field    

Polysukkiini-imidi is mainly used as a fertilizer enhancer in agriculture. It can significantly promote the absorption of nutrients by plants, improve fertilizer utilization efficiency, thereby increasing crop yield and improving crop quality. In addition, polysuccinimide can promote root growth and enhance crop stress resistance, such as drought resistance and disease resistance. At the same time, its use helps improve soil structure and enhance soil fertility, making it a green and environmentally friendly agricultural input.

2、 Polysuccinimide is Used in the Field of Water Treatment     

In the water treatment industry, polysuccinimide and its hydrolysis product polyaspartic acid (PASP) exhibit excellent performance. They can be used as corrosion inhibitors, scale inhibitors, dispersants, etc., effectively preventing equipment corrosion, scaling and other problems in water systems. This feature enables polysuccinimide to be widely used in various scenarios such as cooling water treatment, reverse osmosis membranes, and oilfield recovery water treatment, ensuring the stable operation of water systems and extending the service life of equipment.

3、 Polysuccinimide is Used in the Chemical Industry  

In the field of chemical engineering, polysuccinimide, as an organic synthesis raw material, has a wide range of potential applications. It can participate in various chemical reactions to generate compounds with specific functions. For example, through hydrolysis reaction, polysuccinimide  can be converted into polyaspartic acid, which has a wide range of applications in pharmaceuticals, pesticides, dyes, and other fields. In addition, polysuccinimide can also be used to synthesize other polymer materials or functional additives to meet the diverse needs of the chemical industry.

4、 Polysuccinimide is Used in Other Fields     

In addition to the above-mentioned fields, polysuccinimide has also shown certain application prospects in the fields of medicine, food, and environmental protection. In the field of medicine, it can be used as a precursor or excipient for drugs; In the food industry, it can be used as a food additive or nutritional supplement; In the field of environmental protection, it can be used for sewage treatment, air purification, and other aspects.

In summary, polysuccinimide plays an important role in multiple industries due to its unique properties and wide range of applications. With the advancement of technology and the strengthening of environmental awareness, the market demand for polysuccinimide will continue to grow, and its application areas will also continue to expand and deepen.
