CAS No. 2 6099-09-2
HPMA 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 330C. HPMA has
obvious threshold effect under high temperature (350C) 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 300C 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.
HPMA can also used as additives for cement.

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