CAS No.: 26099-09-2
Structural Formula:
Properties:
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.

Usage:
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.
Package and Storage:
Normally In 250kg net Plastic Drum, IBC drum can
also be used as required.Storage for one year in room shady and
dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted,
flush with water.
