    Polymaleic Acid CAS 26099-09-2

    Polymaleic Acid, frequently abbreviated as PMA and recognized by the formula (C4H2O3)n, is a high-performance solvent-based polymer known for its exceptional calcium carbonate scale inhibition and thermal stability. This chemical substance functions as a potent calcium carbonate inhibitor and dispersant, facilitating the maintenance of heat transfer efficiency in high-temperature industrial cooling systems and multi-stage flash distillation units. In the industrial manufacture of oilfield chemicals and specialized textile auxiliaries, it acts as a critical threshold agent that remains effective under alkaline and hypersaline conditions, ensuring the prevention of mineral deposition on processing equipment surfaces. We provide this material with competitive factory pricing, supporting requirements for customized specifications regarding active content and molecular weight distribution for specific water treatment protocols. All shipments are accompanied by comprehensive MSDS, TDS, COA documentation to ensure full regulatory compliance and are available for bulk supply to support continuous large-scale industrial water management operations.

    Product Description

    polymalic acid

    alias: PolymaleicacidAq; Hydrolysed Polymaleic Anhydride; Hydrolyzed Polymaleic Anhydride; Hydrolized polymaleic anhydride; HPMA

    CAS Number: 26099-09-2

    Molecular formula: (C4H4O4)n

    Molecular weight: ≤2000

    Light yellow to brownish-red clear liquid.

    HPMA is also called polymaleic acid and hydrolyzed polymaleic anhydride.

    package：25kg/drum

    Main uses:

    1) As a descaling agent, it is used for the treatment of cooling water, boiler water, oilfield water injection, and industrial water.

    2) Add to industrial circulating water to slow down and prevent the precipitation and scaling of insoluble substances on the metal surface, and maintain the service life and heat transfer effect of metal equipment.

    3) Used for metal corrosion inhibition. It can form a protective film on the metal surface by compounding with zinc salt, thereby playing a corrosion inhibition role

    FAQ - Technical & Supply Chain

    • Q:

      How is the thermal stability of Polymaleic Acid verified for high-pressure boiler systems?

      A: The technical identity is confirmed via CAS 26099-09-2, and its performance is typically measured by its ability to inhibit scale at temperatures exceeding 300°C, ensuring reliable protection in high-stress industrial thermal environments.
    • Q:

      Is Polymaleic Acid suitable for use in high-salinity oilfield water injection?

      A: Yes, this material is typically applied as a primary scale inhibitor in saline oilfield environments due to its superior tolerance to calcium and magnesium ions, intended for professional industrial chemical treatment rather than general consumer use.
