CAS No. 26677-99-6
Structural Formula:
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 (300℃).
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.
