CAS No 26099-09-2 Dequest P9000
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.

for one year in room shady and dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted, flush with
water.
