Composition:HPMA Homopolymer of maleic acid uses the process which maleic acid anhydride direct hydrolysis synthesis organic acid polymer.
HPMA Characteristic:

1.HPMA Homopolymer of maleic acid process is non-chemistry pollution and doesn’t involve xylene, toluene, etc organic reagent.
2. HPMA homopolymer of maleic acid can dissolove in water, and high chemical stability and high thermostability.
3.The toxicity is small, HPMA polymaleic acid can be degraded by the microbial, to human, animal is harmless.
Homopolymer Of Maleic Acid Application:

HPMA Homopolymer of maleic acid is mainly used in cooling water systems, boiler water systems, oilfieic injection systems, sugar mill evaporate systems, reverse osmosis systems, desalination systems.
Application Method: General amount used 2-20mg/L, in order to prevent the steel effectively corrosion, with organic phosphate compound use 2-5mg/L, with zinc salt use 1-2mg/L.
Packing: 25KG or 200KG net in plastic drum.
Storage: Kept in a well-closed, dry and cool place.
