CAS No. 26099-09-2
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 330℃. HPMA 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,
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
HPMA has good scale inhibition (98%)
and scale stripping properties. When used together with zinc
salts, it can effectively inhibit carbon steel corrosion.
