Product Name: Hydrolyzed Polymaleic Anhydride(HPMA)
Cas:26099-09-02
1.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…
