Polymaleic Acid (PMA)


Molecular Weight:  About 1000

Molecular Formula & Molecular Structure:

 

Properties:

PMA is a solvent-based maleic acid hopolymer, with obvious threshold inhibition and crystal modification, and average molecular weight around 1000. It is the superior calcium carbonate inhibitor in high hardness, high alkalinity, and high temperature severe water conditions and a multifunctional formulation support agent in industrial water systems and other related applications.

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.

Specification:
