Product Description
Hydrolyzed Polymaleic Anhydride
(HPMA)
CAS No. *********2
Dequest：P***0
Properties:
HPMA is a low molecular weight polymeride, with average molecular
weight ******0. No toxicity, soluble in water, high chemical and
thermal stability, decomposed temperature above **0℃. HPMA has
obvious threshold effect under high temperature (**0℃) 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 **0℃ with effective time as long
as **0 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.

Usage:
HPMA is usually used together with organic phosphonate at dosage of
***5ppm for circulating cool water system, oilfield fill water,
crude oil dewatering and low-pressure boilers. HPMA has good scale
inhibition (*8%) and scale stripping properties. When used together
with zinc salts, it can effectively inhibit carbon steel
corrosion.
HPMA can also used as additives for cement.
