Detailed introduction

Copolymer of Maleic and Acylic Acid ( MA/AA )

CAS No.26677-99-6

Structural formula:

Performance and Applications:

MA/AA It is a low-molecular-weight polyelectrolyte prepared by copolymerizing maleic acid and acrylic acid in a specific ratio. It exhibits strong dispersing properties toward carbonates and other substances, possesses high thermal stability, and can be used in… 300℃ It can be used under high-temperature and other harsh conditions and exhibits excellent compatibility and synergistic effects when combined with other water treatment chemicals.

MA/AA It exhibits excellent inhibition of scale formation, including phosphate scale. Owing to its superior scale‑inhibition and high‑temperature resistance, it is widely employed in low‑pressure boilers, district heating systems, central air‑conditioning systems, and various circulating cooling water systems; it can also be used as a chelating dispersant in the textile printing and dyeing industry.
