Polyepoxysuccinic Acid (Sodium Salt)


Polyepoxysuccinic acid (sodium salt) 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 better effects than ordinary organophosphines. When built with organophosphates, the synergism effects are obvious.

Polyepoxysuccinic acid sodium has good biodegradation properties. It can be widely used in circulating cool water systems with high alkaline, hardness, and pH value. It can be operated under a high concentration index. Polyepoxysuccinic acid sodium salt synergizes well with chlorine and other water treatment chemicals.

Polyepoxysuccinic acid sodium can be used in an oilfield refill water system, crude oil dehydration, and boiler. In addition, it can be used in circulating cool water systems of steel, petrochemical, power plant, and medicine.

Polyepoxysuccinic acid sodium can also be used in the boiler water, circulating cool water, desalination plant, and membrane separation in the situation of high alkaline, hardness, high pH value, and high concentration index. It can be used in detergent fields.
