Hydrolyzed Polymaleic Anhydride

CAS No. : 26099-09-2

Properties
Hydrolyzed Polymaleic Anhydride is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. Hydrolyzed Polymaleic Anhydride has obvious threshold effect under high temperature (350℃) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. 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, Hydrolyzed Polymaleic Anhydride 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, Hydrolyzed Polymaleic Anhydride has good corrosion inhibition effect when used together with zinc salt. Hydrolyzed Polymaleic Anhydride can also used as additives for cement.

Usage
Hydrolyzed Polymaleic Anhydride is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. Hydrolyzed Polymaleic Anhydride has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.

Package and Storage
Normally In 250kg net Plastic Drum, IBC drum can also be used as required.Storage for 12 months in room shady and dry place.

Safety Protection
