Poly Maleic Acid (PMA) is a low molecular weight polymerize, with average molecular weight 800-1000. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330 Deg. C. Poly Maleic Acid (PMA) has obvious threshold effect under high temperature (350 Deg 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 Deg. C with effective time as long as 100 hours. Polymaleic acid is the utmost suitable product or additive used as antiscaling agent for all heated water processes such as Sea water desalination, condenser water, vapor generating steam, all other heated watersteam processings. It is standing and functioning superiorly as anti scaling at normal or elevated temperature due to its crystal modification effect. Other polymers, or additive that are usually applied for antiscaling do not show this superiority.
