Detailed introduction

Copolymer of Phosphono and Carboxylic Acid ( POCA )

Also known as: POCA 、 Principal Component Analysis

CAS No.71050-62-9

Performance and Applications:

POCA It involves introducing a phosphonic acid group onto the original carboxylate moiety, exhibiting excellent dispersing performance against calcium carbonate and calcium phosphate scale in circulating cooling water, as well as effective inhibition of barium sulfate, strontium sulfate, and silica scaling. When compounded with other organic phosphonates and copolymers, it demonstrates synergistic effects. This product features a broad compatibility with various water qualities, good chemical stability, and strong resistance to chlorine oxidation, and is primarily used for scale inhibition and corrosion control in industrial circulating cooling water systems and oilfield produced‑water reinjection systems.
