Phosphino Carboxylic Acid Polymer(PCA)
Ⅱclass CAS No. 71050-62-9
Molecular Formula：(C3H4O2•H3O8P•Na)x
Properties:
By introducing the phosphonic group into a carboxylic group, Phosphino Carboxylic Acid Polymer has good dispersion properties for the scale of calcium carbonate and calcium phosphate in the circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate, and silica scale. Phosphino Carboxylic Acid Polymer has advantages in a wide range of water quality, chemical stability, strong chlorine tolerance, etc. Phosphino Carboxylic Acid Polymer can be used as a scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
Ⅱclass product performance is equivalent to BWA Belsperse 164.
