Polyaspartate Scale Inhibitor
CAS Number: 181828-06-8
Polyaspartate (PASP sodium salt) is the neutralized, water-soluble form of polyaspartic acid used as a biodegradable scale inhibitor and dispersant in industrial water treatment. It effectively inhibits calcium carbonate, calcium sulfate, and barium sulfate scale formation and disperses iron oxide and clay deposits. As a readily biodegradable polymer, it is preferred in environmentally sensitive applications over conventional phosphonate and polyacrylate inhibitors.
