Hydrolyzed Polymaleic Anhydride (HPMA) - Product

Place of Origin : Zaozhaung,China

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 330C. HPMA has obvious threshold effect under high temperature (350C) 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 300C with effective time as long as 100 hours.
