CAS No. 26099-09-2
Dequest：P9000
Structural Formula:
HPMA is a low molecular weight polymeride, with an average molecular weight of 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has an obvious threshold effect under a high temperature (350℃) and high pH(8.3)level, suitable for being used in alkaline water systems 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 plants of flash vaporization equipment, low-pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. Besides, HPMA has a good corrosion inhibition effect when used together with zinc salt.
Can also be used as boiler antiscalant chemicals

HPMA is usually used together with organic phosphonate at a dosage of 1-15ppm for circulating cool water systems, oilfield fill water, crude oil dewatering, and low-pressure boilers. HPMA has good scale inhibition (98%) and scales stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.
HPMA can also be used as an additive for cement.
