Properties:
MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good
dispersant performance against carbonate and scale inhibition for phosphate. it has good thermal
stability, can be used under high temperature (300âÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ). 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. It can also be used as chelating dispersants in woven and dyeing fields.

Usage:
MA/AA is used in circulating cool water system, medium or lower pressure boiler and distillation system in
which high temperature is usually encountered. MA/AA can be used alone or together with other
organic phosphates. When used together, the dosage of 2-10mg/L is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments.
