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
yellow to umber transparent liquid

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
