Hydrolyzed Polymaleic Anhydride used in many
industry applications

Hydrolyzed polymaleic anhydride (HPMA) is a water-soluble polymer known for its excellent scale inhibition, dispersing, and chelating properties. It is widely used in various industrial applications. Here's a list of some of its industrial uses:

  1. Water Treatment: HPMA is extensively used in water treatment processes as a scale inhibitor and dispersant, preventing the formation of scale deposits in cooling water systems, boilers, and desalination plants.
  2. Detergents and Cleaners: It is used in detergent and cleaning formulations to improve their performance by preventing the precipitation of calcium and magnesium salts, thus enhancing cleaning efficiency.
  3. Oil and Gas Industry: HPMA is used in the oil and gas industry as a scale inhibitor in oilfield operations, including drilling, production, and water injection systems, to prevent scale buildup and improve flow efficiency.
  4. Paper and Pulp Industry: It is utilized in the paper and pulp industry as a dispersant to improve the processing and quality of paper products by preventing the agglomeration of particles.
  5. Textile Industry: HPMA is used in textile processing as a dispersant and scale inhibitor, enhancing dyeing processes and preventing scale formation in equipment.
  6. Mining Industry: It is used in mining operations to prevent scale formation in process water circuits, thereby improving the efficiency and lifespan of equipment.
  7. Concrete and Cement Additives: HPMA is used as an additive in concrete and cement formulations to enhance their properties, such as workability and strength, by dispersing cement particles and preventing scale formation.
  8. Metalworking: It is employed in metalworking fluids as a dispersant and corrosion inhibitor, helping to protect metal surfaces and improve the performance of cutting and grinding operations.
  9. Food and Beverage Industry: HPMA is used in the food and beverage industry to prevent scale formation in equipment such as evaporators, heat exchangers, and pasteurizers, ensuring efficient and hygienic operations.
  10. Personal Care Products: It is used in personal care products, such as shampoos and conditioners, as a dispersant and chelating agent, improving product performance and stability.
  11. Desalination: HPMA is used in desalination plants to prevent scale formation on membranes and heat exchangers, thereby enhancing the efficiency and lifespan of the desalination process.
  12. Industrial Cleaning: It is used in industrial cleaning formulations to enhance the removal of scale and deposits from surfaces and equipment, improving cleaning efficiency and reducing maintenance costs.
