CAS No. 26099-09-02

Structural Formula:

11.jpg


Product Grade:Industrial


Application:

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has obvious threshold effect under high temperature (350℃) 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℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA 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, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.

HPMA, or Hydrolyzed Polymaleic Anhydride, is a versatile water treatment chemical with the CAS number 26099-09-02. Derived from Polycarboxylic Acid, HPMA is widely utilized for its outstanding scale and corrosion inhibition properties. It is highly effective in preventing scale formation and reducing corrosion in water systems. With its excellent thermal stability and dispersant capabilities, HPMA ensures the efficient operation and prolonged lifespan of industrial equipment, making it an essential component in various industrial applications.
