Sodium of Polyaspartic Acid(PASP)181828-06-8,35608-40-61

Polyaspartic acid sodium salt (PASP) is a polymer compound with a light yellow powder appearance, which is easily soluble in water and does not contain phosphorus elements, effectively avoiding the problem of eutrophication of water caused by phosphorus discharge. In the field of water treatment, it not only has good dispersibility, low toxicity, and biodegradability, but also has a wide range of applications in scale prevention, flocculation, sewage treatment, and membrane pollution control.

Sodium Salt of Polyaspartic Acid (PASP) CAS No.181828-06-8,35608-40-6 is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASP have high chemical activity in aqueous solution; in each structural unit of PASP, the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, PASP has good hydrophilicity and water solubility.
