Hydrolyzed Polymaleic Anhydride (HPMA)
CAS No. 26099-09-2
EINECS: 607-861-7
Molecular Formula: (C4H404)n
Product Description:
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 330ºC. HPMAhas obvious threshold effect under high temperature (350ºC) 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 300ºC with effective time as long as 100 hours.
Application :
HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.
