Product Overview
Polysuccinimide is a sustainable and environmentally friendly biodegradable polymer material with distinctive solvent tolerance and selective dissolution characteristics. In standard physical state, it exists as uniform white powder with stable molecular structure and excellent chemical inertness against daily aqueous and alcoholic solvents. Its special response to strong polar solvents allows targeted processing and structural modification, greatly expanding its industrial applicability.
As a precursor polymer with excellent degradability, polysuccinimide can undergo hydrolysis reaction to generate polyaspartic acid, a green phosphorus-free functional derivative. This endows the entire material system with eco-friendly, zero-pollution and recyclable advantages, conforming to modern green chemical and environmental protection production standards.

Application Advantages
In environmental water treatment, its hydrolyzed product polyaspartic acid acts as an efficient scale inhibitor and heavy metal adsorbent, effectively mitigating pipeline scaling and purifying wastewater heavy metal pollutants without introducing phosphorus pollution.
In agricultural fields, the material serves as an efficient fertilizer synergist, which optimizes nutrient absorption efficiency of crops and promotes healthy plant growth, realizing precise and efficient agricultural planting.
In biomedicine and material science, polysuccinimide can be chemically modified to prepare biocompatible slow-release drug carriers, achieving stable and long-term drug release. It is also widely blended with other polymer materials to develop fully biodegradable plastic products, solving the environmental pressure of traditional plastic pollution.
Additionally, it shows excellent application potential in the petrochemical and daily chemical industries. It can be used as a functional additive for drilling fluid systems to improve construction stability, and also serves as a mild moisturizing ingredient in cosmetic formulations, delivering safe and efficient daily chemical application performance.
