Poly Maleic
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 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. 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.

Uses:
Poly Maleic Acid (PMA) is usually used together with organic
phosphonate at dosage of 1-15ppm for circulating cool water system,
oilfield fill water, crude oil dewatering and low-pressure boilers.
Poly Maleic Acid (PMA) has good scale inhibition (98%) and scale
stripping properties. When used together with zinc salts, it can
effectively inhibit carbon steel corrosion.
