Polyepoxysuccinic Acid (PESA)
Synonym: Polyoxirane-2,3-Dicarboxylic Acid
CAS No. :1528-98-7
Molecular Formula: HO(C4H2O5M2)n
Molecular weight: 400-1500
Structural Formula:
Properties:
Polyepoxysuccinic Acid is a multivariate scale and corrosion inhibitor with non-phosphor and non-nitrogen. It has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride, and silica scale, with effects better than ordinary organophosphines. When built with organophosphates, the synergism effects are obvious.
Polyepoxysuccinic Acid has good biodegradation properties; it can be widely used to circulate cool water systems in high alkaline situations, high hardness, and high pH value. PESA can be operated under a high concentration index. PESA has good synergism with chlorine and other water treatment chemicals.
