Hydrolyzed Polymaleic Anhydride (HPMA)
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℃. It 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…
