Polymaleic Acid

Polymaleic Acid(CAS:26099-09-2)

Supplier: Polyacrylic acid, polyacrylic acid sodium, hydrolyzed polymaleic anhydride

Cas 26099-09-2 dequest: p9000 Properties: Hpma(hydrolyzed polymaleic anhydride) 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 330 centigrade. Hpma(hydrolyzed polymaleic anhydride) has obvious threshold effect under high temperature (350 centigrade) 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 centigrade with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, hpma(hydrolyzed polymaleic anhydride) 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(hydrolyzed polymaleic anhydride) has good corrosion inhibition effect when used together with zinc salt. Hpma(hydrolyzed polymaleic anhydride) can also used as additives for cement. Appearance Clear to umber transparent liquid Solid content % 48.0 min Bromine value mg/g 80.0 max Average molecular weight 450 min Ph(1% solution) 2.0-3.0 Density (20 centigrade)g/cm3 1.18 min Usage: Hpma(hydrolyzed polymaleic anhydride) 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(hydrolyzed polymaleic anhydride) 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.

Polyacrylic acid (paa) Cas: 9003-01-4 Properties: Paa is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. Paa can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. Paa is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc. Usage: Paa can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When used alone, 1-15mg/l is preferred.
