CAS No. 26099-09-2
HPMA; Homopolymer of maleic acid; Hydrolyzed Polymaleic Anhydride; poly(maleicacid); Polymaleic Acid; maleic acid polymer; Polymaleic Acid
HPMA has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours.
Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems.
In addition, HPMA has good corrosion inhibition effect when used together with zinc salt.
