Properties of  MA/AA:

MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. MA/AA has good dispersant performance against carbonate and scale inhibition for phosphate. MA/AA has good thermal stability, can be used under high temperature (300C). MA/AA has good compatibility when used together with other agents. MA/AA is widely used in low-pressure boiler, centralized heating, centralized air-conditioner and circulating cool system. MA/AA can also be used as chelating dispersants in woven and dyeing fields.
