Molecular Weight: 400-800
HPMA is a low molecular weight polymeride, with average molecular weight 400-800, non-toxic, 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 systems. 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.

HPMA is usually used together with organic phosphonate for circulating cooling water system, oilfield fill water, crude oil dewatering and low-pressure boilers.
HPMA has good scale inhibition (98%) and scale stripping properties. When EDTMPS ratio of HPMA is 1:3, it can be used for low-pressure boiler furnace water treatment. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.
