HL-203 Copolymer of Maleic and Acrylic Acid (MA/AA)
CASNo. 26677-99-6
StructuralFormula:
Properties:MA-AA is a low molecular weightpolyelectrolyte with strong dispersibility to carbonates and other substances.It has high thermal stability and can be used under harsh conditions such ashigh temperatures of 300 ℃. It has good compatibility and synergistic effectwith other water treatment agents, and has a good inhibitory effect on theformation of scale, including phosphates. And the scale inhibition performanceis equivalent to or slightly higher than HPMA. Due to its excellent scaleinhibition and high temperature resistance, this product is widely used inlow-pressure boilers, central heating, central air conditioning, and variouscirculating cooling water systems. This product can also be used as a chelatingdispersant in the textile printing and dyeing industry.
