Hydrolyzed Polymaleic Anhydride (HPMA)

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical thermal stability, decomposed temperature above 330°C. HPMA has obvious threshold effect under high temperature (350°C) high pH(8.3)level, suitable to be used in alkaline water system built with agents. It has good scale inhibition against carbonate phosphate scales under temperature 300°C with effective time as long as 100 hours. Due to its good scale inhibition 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, industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives fcement.
 

Specification

Usage

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