It 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, polymaleic acid is widely used in the desalination plant of flash vaporization equipment, low-pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems.

In addition, hydrolyzed polymaleic anhydride has good corrosion inhibition effect when used together with the zinc salt. Poly maleic anhydride can also be used as additives for cement.

Hydrolyzed poly maleic anhydride is usually used together with organic phosphonate at a dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering, and low-pressure boilers.

Poly maleic anhydride has good scale inhibition (98%) and scales stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.
