Product Details

Homopolymer of Maleic Acid or Hydrolyzed Polymaleic Anhydride

HPMA

CAS Number: 26099-09-02

Molecular Weight: >700

Application Notes:HPMA has obvious threshold effect under high temperature (350°C) 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°C with effective time as long as 100 hours. Due to its good  scale inhibition and high temperature tolerance properties.

Recommended Uses:

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. It can be  used in combination with phosphonates to improve performance and reduce  phosphonate levels and thus provide a superior alternative to acrylate-based  polymers.
