Sell Hydrolyzed Polymaleic Anhydride (HPMA)

Description

[CAS No.] *********2 Properties: This product is an organic aliphatic acid polymeride, with average molecular weight in range of ******0. No toxicity, Soluble in water, high chemical and thermal stability. Since its dissociation temperature is above **0&#***1;, the product exhibits obvious threshold effects under high temperature (**0&#***1;) and high pH&#****8;8.3&#****9;level, suitable to alkali water quality or built with other water treatment agents. It shows good antiscale property against carbonate and phosphate scales under temperature **0&#***1; with effective time as long as **0 hours. This product can also be used together with crude oil dewatering demulsifiers. Due to its excellent antiscale and high temperature resistance properties, this product is widely used in desalination plant of flash vaporization equipment low pressure boiler, steam locomotive, crude oil evaporation, water and petroleum pipeline, and industrial circulating cool water systems. In addition, this product shows excellent corrosion inhibition effect. When used together with zinc salt, its effect will be even better. This product can also used as additives for cement.
