Poly Malic Acid - PMA


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 °C.

 

Poly Maleic Acid (PMA) has obvious threshold effect under high temperature (350 °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 °C with effective time as long as 100 hours.

 

Due to its good scale inhibition and high temperature tolerance properties, Poly Maleic Acid (PMA) 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, Poly Maleic Acid (PMA) has good corrosion inhibition effect when used together with zinc salt. Poly Maleic Acid (PMA) can also used as additives for cement.

 

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 water/steam 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.
