Hydrolyzed Polymaleic Anhydride Typical Properties

Hydrolyzed Polymaleic Anhydride application:

• Industrial Water Treatment:

  • High-Temperature Scale Inhibitor: Widely used in industrial circulating cooling water systems, low-pressure boilers, oilfield water injection, and seawater desalination plants. Highly effective against calcium carbonate scale buildup under high temperature and high pH conditions.

  • Corrosion & Dispersion Helper: Disperses silt, and inorganic sludge deposits, maintaining clean heat-exchanger surfaces.

• Textile & Dyeing Auxiliaries:

  • Chelating & Dispersing Agent: Used as a non-foaming chelating agent in textile pre-treatment, peroxide bleaching, and dyeing processes to sequester heavy metal ions and prevent spot staining.

• Reverse Osmosis & Desalination:

  • RO Membrane Antiscalant: Primary active component in reverse osmosis (RO) antiscalant formulations for thermal distillation and RO seawater desalination plants.
