Phosphinocarboxylic Acid Copolymer, PCA POCA Polymer


Through the introduction of a phosphonic group into a carboxylic group, the phosphinocarboxylic acid copolymer has good dispersion property for the scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale.

The POCA polymer has advantages in a wide range of water quality, chemical stability, strong chlorine tolerance, etc. PCA polymer can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
