Understanding Polyaspartic Acid Structure and Iminodisuccinate Derivatives  

Polyaspartic Acid Structure: The Backbone of Biodegradability

The polyaspartic acid structure is a repeating chain of aspartic acid units, forming a water-soluble, biodegradable polymer. Its unique helical configuration enables exceptional metal ion chelation and scale inhibition. Hebei Xiangdu’s polyaspartic acid derivatives are widely used in water treatment, agriculture, and detergents due to their non-toxic, eco-friendly properties.

Tetrasodium Iminodisuccinate: A Versatile Chelating Agent

Tetrasodium Iminodisuccinate (TSIDS) is a biodegradable alternative to phosphates and EDTA. With four sodium ions in its structure, it effectively binds calcium, magnesium, and heavy metals in industrial cleaning and textile processing. Verify that your supplier’s TSIDS meets ISO 14001 environmental management standards.
