    Properties

    Yuanlian PSI (polysuccinimide) is an intermediate product in the production of Yuanlian PASP (sodium polyaspartate).

    Polysuccinimide is a beige solid powder that is virtually insoluble in water. PSI can hydrolyze to PASP very slowly in water. This long-time slow-releasing PASP property can be used for special purpose, for example for scale inhibition in water treatment, saline soil ameliorator.
