Trade Lead Description:
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.C. HPMA has obvious
threshold effect under high
temperature (350.C) 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.C 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.
