    Properties

    Polyaspartic acid (abbreviated PASP) is a kind of biodegradable green biopolymer materials. Its molecules contains abundant amido bond, carboxyl and other active groups. The special molecular structure of PASP ensures that it has good dispersing ability, corrosion inhibiting properties, excellent capabilities of chelation, adsorption, excellent biodegradability and environmental friendly characteristics. 

    Polyaspartic acid Sodium salt (PASP Na Salt) is widely used in water treatment chemicals, detergent, saline soil ameliorator, etc.

    PASP chelated micronutrient, such as Potassium (K), Calcium (Ca), Magnesium (Mg), Zinc (Zn), can be used for chelated micronutrients fertilizer, saline soil ameliorator.
