HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.
We offer a wide range of high performance industrial and process water and waste water treatment chemicals. These chemicals have been specifically developed to significantly improve the management problems commonly associated with the treatment of industrial and process waters. Our treatment have been specifically formulated for the effective treatment of boilers, cooling towers and cooling water systems; wastewater and industrial effluents. The broad range of water treatment chemical supply includes HEDP 60%, DETPMP and ATMP.

Hydrolyzed polymaleic anhydride (hpma) Cas no.: 26099-09-2 Structural formula: Properties: 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 330íµ. Hpma has obvious threshold effect under high temperature (350íµ) and high phú¿8.3ú¬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 300íµ 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. Specification: Items Index Appearance Clear to umber transparent liquid Solid content % 48.0 min Bromine value mg/g 80.0 max Average molecular weight 450 min Phú¿1úÑ solutionú¬ 2.0-3.0 Density ú¿20íµú¬g/cm3 1.18 min Usage: Hpma is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. Hpma has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion. Package and storage: Normally in 250kg net plastic drum, ibc drum can also be used as required.Storage for one year in room shady and dry place. Safety protection: Acidity, avoid contact with eye and skin, once contacted, flush with water. 250kg net plastic drum
