Hydrolyzed Polymaleic Anhydride (HPMA), CAS No. 26099-09-2, is a low molecular weight polymer with non-toxic, water-soluble, and high chemical and thermal stability. It is widely used in water treatment and industrial applications. The following is a detailed introduction to HPMA:
HPMA is a hydrolysis product of maleic anhydride. Its molecular structure contains multiple carboxylic acid groups, which impart excellent chelating and dispersing abilities.
* Appearance: Pale yellow to brown, transparent liquid.
* Molecular Weight: Average molecular weight 400-800.
* Solubility: Easily soluble in water, forming a transparent solution.
* Stability: Highly chemically stable, with a thermal decomposition temperature exceeding 330°C. HPMA remains active even at elevated temperatures (e.g., 350°C) and high pH (e.g., 8.3).
Non-toxic and environmentally friendly. However, in case of contact with eyes, rinse immediately with plenty of running water and seek medical attention.

* Calcium and Magnesium Salt Deposition Inhibition: By chelating calcium and magnesium ions in water, it prevents the formation of scales such as calcium carbonate and calcium phosphate.
* High Temperature Tolerance: Effectively inhibits scale at 300°C for up to 100 hours, making it suitable for high-temperature water systems.
* Synergistic Effect: When used in combination with organic phosphonates, it achieves a scale inhibition rate of up to 98%, significantly improving water treatment efficiency.
* Carbon Steel Protection: When combined with zinc salts, it forms a protective film on metal surfaces, effectively inhibiting corrosion.
* Applications: Suitable for corrosion protection in equipment such as circulating cooling water systems, oilfield water injection, and low-pressure boilers.
Disperses suspended particles in water, preventing deposition and maintaining system cleanliness.
*Industrial Circulating Water: Used for scale and corrosion prevention in circulating cooling water systems in power plants, chemical plants, and other applications.
*Boiler Water Treatment: Prevents scaling in low-pressure boilers, extending equipment life.
*Seawater Desalination: Inhibits salt scale formation in flash evaporation equipment, improving desalination efficiency.
*Oilfield Water Injection: Prevents scaling in injection pipes, ensuring oil well production efficiency.
*Crude Oil Evaporation: Reduces evaporator scaling and reduces energy consumption.
*Oil Pipelines: Inhibits corrosion on pipeline walls, extending service life.
*Cement Additive: Improves cement fluidity and enhances workability.
*Detergent: Used as a water softener to enhance cleaning performance.
