The growing demand for eco-friendly and high-performance materials has propelled the development of polyaspartic acid-based products, leading to the establishment of dedicated manufacturing facilities worldwide.

Manufacturing Process

The production of polyaspartic acid ammonium salt typically involves a two-step process synthesis of polyaspartic acid followed by the neutralization with ammonium hydroxide. The initial step involves a polycondensation reaction between aspartic acid and itself under controlled conditions. This reaction generally occurs at elevated temperatures, facilitating the removal of water to drive the reaction forward. As a result, polyaspartic acid chains are formed, which can vary in molecular weight depending on reaction conditions.

In the subsequent neutralization step, the synthesized polyaspartic acid is reacted with ammonium hydroxide or ammonium salts. This not only neutralizes the acidity of polyaspartic acid but also improves its solubility and alters its properties for various applications. The final product, polyaspartic acid ammonium salt, is characterized by high stability, low toxicity, and excellent compatibility with other materials.
