Product Short Description: it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems. Hydrazine is mainly used as a foaming agent in preparing polymer foams. No oxygen is entering the boiler with the feed water when hydrazine is present in the water. Product Description: No oxygen is entering the boiler with the feed water when hydrazine is present in the water. The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout. Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems. Hydrazine is mainly used as a foaming agent in preparing polymer foams. No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
