No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has obvious threshold effect under high temperature (350℃) 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℃ 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 Pale yellow 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℃)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.

Company Information (Shandong Taihe Water Treatment Chemicals Company Limited)

Company Profile: Shandong Taihe water treatment Co., Ltd. (former Zaozhuang Taihe chemical factory) is located in Zaozhuang City, south of Shandong Province. The company founded in 1998, is one of the largest and the most professional water treatment chemicals factories in China, and can manufacture all kinds of water treatment chemicals. The total yields reach to 40,000 tons now. The products are widely used in industrial circulating water system, boiler and heating water system. To meet the needs of different fields, some solid products such as organophosphoric acids and the relevant sodium salts have been developed recently in our factory, including high purity grade and ordinary grade. Some polymer solid products have also been developed. To cooperate with our clients for water quality analysis and treatment process planning, we have set up a synthesis and application laboratory and several research projects have been doing here. >> More Website URL: http://www.bridgat.com/u2867
