Acrylic acid maleic anhydride copolymer can be used at high temperatures (300℃). In addition, this acrylic maleic copolymer has good compatibility when used together with other agents.

MA-AA is widely used in low-pressure boilers, centralized heating, air-conditioners, and circulating cool systems. It can also be a chelating dispersant in woven and dyeing fields.


Acrylic acid maleic anhydride copolymer can be used alone or with other organic phosphates. When used together, the dosage of 2~10mg/L is preferred. Experiments should determine the dosage for woven & dyeing and accessory detergent.
