Description    
Polymaleic acid is the homopolymer of maleic acid. 
​Polymaleic Acid is very stable in presence of chlorine and other oxidizing biocides. 
​Polymaleic Acid has good scale inhibition and high temperature resistance properties. 
Therefore, it can be used in the water desalination plants. 
​Polymaleic Acid is also an excellent calcium carbonate antiscalant upon high temperature and in the high alkaline cooling water systems. 
In addition, it can be used in combination with zinc salts as a corrosion inhibitor. 
​Polymaleic Acid can also be used as concrete additive and for crude oil evaporation.
​Polymaleic Acid can be manufactured through the polymerization of maleic anhydride I an aromatic hydrocarbon upon 60° to 200° C.

Polymaleic Acid is a maleic acid homo polymer, with obvious threshold inhibition and crystal modification, and average molecular weight around 1000.
​Polymaleic Acid 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.

Polymaleic Acid 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.

Usage:
Polymaleic Acid has better performance when combined with phosphonates than when phosphonates used alone. 
Polymaleic Acid is compatible with quaternary ammonium compounds, while not affected by chlorine or other oxidizing biocides under normal use conditions.

Polymaleic Acid has a high chemical and thermal stability; it is not toxic, is soluble in water and acts as a complexing agent for some cations.

Regarding its functionality in the soil, it displaces the Na+ cations allowing it to seep through the soil’s profile, replacing it with Mg+2 and Ca+2. 
​Polymaleic Acid unblocks sodium and prevents the counterproductive effect that it produces on the soil’s structure and aggregates.

This property has clear effects on agriculture; the Na+ cation is by far the least desirable due to the de-structuring and disaggregation effect it has on the soil. 
In addition, polymaleic acid itself acts as a complexing/ aggregating agent, contributing to its physical and chemical formation.

This reduces the harmful effects that the possible accumulation of salt has on the soil profile, in addition to improving structural properties, formation of aggregates, improvement in the CEC (cationic exchange capacity) as well as the soil’s texture and composition (through simple salt elimination).

Description
 
Polymaleic acid is the effective scale inhibitor which mainly used for low pressure boilers, industrial cooling water system, oilfield water pipeline, crude oil dehydration.

A polymaleic acid (PMA) specific antibody test kit has been developed to monitor PMA in cooling water systems. This method has been used to confirm the Langelier Saturation Index (LSI) curve for PMA alone and with a phosphonate in pilot cooling water tests. 
A number of field tests were conducted with the antibody test kit that demonstrate the value of monitoring the PMA for deposit control and system efficiency.
