Polyepoxysuccinic Acid (PESA)

Details:

Description
Poly(1-oxacyclopropane-2,3-dicarboxylic acid) is the chemical name of Polyepoxysuccinic Acid(PESA).
It is a non-phosphorus, non-nitrogen "green" environmentally friendly multi-element scale and corrosion inhibitor. It has good scale inhibition and dispersion performance for calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride and silica scale in water, and the scale inhibition effect is better than that of commonly used organic phosphine scale inhibitors. The combination of PESA and phosphonate has a good synergistic effect. At the same time, PESA has a certain corrosion inhibitory effect and is a multi-element scale inhibitor.

PESA has good biodegradability and a wide range of applications. It is especially suitable for using in circulating cool water system under situation of high alkaline, high hardness and high pH value, and can achieve high concentration multiple operation. PESA has good compatibility with chlorine and good compatibility with other agents.
