50% Phosphino Carboxylic Acid Polymer(PCA) 30%
CAS No. 71050-62-9
Through the introduction of phosphonic group into carboxylic group,
PCA has good dispersion property for 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. PCA has advantages in wide range of water quality, chemical
stability, strong chlorine tolerance, etc. PCA can be used as scale
and corrosion inhibitor in circulating cool water system and
oilfield refill water system.
