Hydrolyzed Polymaleic Anhydride (HPMA) CAS NO.26099-09-2

Hydrolyzed polymaleic anhydride HPMA

Hydrolyzed Polymaleic Anhydride (HPMA)
Alias: polymaleic anhydride, polyhorse, polymaleic acid
CAS No. 26099-09-2

1. Performance and use:
HPMA generally has a relative molecular weight of 400-800; Non-toxic, soluble in water, high chemical and thermal stability, decomposition temperature above 330℃; HPMA is suitable for alkaline environments.
HPMA is widely used in seawater desalination flash plant, low pressure boiler and industrial circulating cooling water because of its excellent scale inhibition and high temperature resistance. And has a certain corrosion inhibition effect, with zinc salt compound corrosion inhibition effect is better, can also be used in cement admixture, saline-alkali soil amendment.
2. Technical indicators

3.Use method
HPMA alone when the general use of concentration of 1-15mg/L, often combined with organic phosphonate, used for circulating cooling water treatment and high-pressure boiler furnace treatment, has a good inhibition of scale generation and peeling old scale, scale inhibition rate of up to 98%, EDTMPS and HPMA according to 1:3 ratio, can be used for low-pressure boiler furnace water treatment; When combined with zinc salt, it can effectively prevent the corrosion of carbon steel.

4. Packaging and storage
HPMA is packed in plastic drums, 25kg or 250kg per barrel, or according to user requirements. The storage period is twelve months.

5. Security protection
HPMA is acidic, pay attention to labor protection during operation, should avoid contact with skin, eyes, etc., rinse with a lot of water after contact.
