Molecular formula: HO (C₄H₂O₅M₂) nH          Relative molecular mass: 400-5000

Structural formula:

I. Product Property

PESA is a multivariate scale and corrosion inhibitor with the most outstanding features of non-phosphor, non-nitrogen and environmental friendliness. It has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale, with better effects than that of ordinary organophosphines. When built with organophosphates, the synergism effects are obvious. With stable product quality and good formulation performance, this product possesses obvious effect of formulation and synergism. Therefore, PESA is a multivariate scale inhibitor with effect of corrosion inhibition to some degree.

PESA has good biodegradation properties and it can be widely used in circulating cool water system in high alkaline, high hardness and high pH value. PESA can be operated under high concentration index. PESA has good synergism with chlorine and other water treatment chemicals.
