Hydrolyzed Polymaleic Anhydride (50% HPMA) CAS NO.26099-09-2

Founded in 2003, Nine Continent Company (hereinafter referred to as NCC) has set up three major production bases in China, headquartered in the BioBay of Suzhou Industrial Park. Suzhou is a very beautiful city with a long history, convenient transportation (only 20 minutes' drive from Suzhou to Shanghai) and many big international enterpries.

NCC’s rapid and stable development enables it to become a leading manufacturer of water treatment chemicals in China, with a turnover of RMB260 million in 2014 in domestic market. The product families include organic phosphonic series, organic phosphate salts, polycarboxylic antiscalant, corrosion inhibitors, chelating agents, dispersants, biocide, algicide and etc., covering wide ranges from single to complex agents. The products are widely used in circulating water system, boiler and heating water system in fields such as steel & iron, petrochemical, power plant, RO systems, textiles and medical industries.

Production Base

NCC owns a 1500-square-meter nanotechnology R&D center located in the BioBay of Suzhou Industrial Park, equipped with such technical laboratories as R&D laboratories, application laboratories, coating room, constant temperature and humidity room, printing room, electron microscopy room and etc. The R&D center is also equipped with more than 50 instruments including R&D instruments, wet-end instruments, coating instruments, printing instruments, physical property detecting instruments, particle size instruments and electron microscopy instruments, with a total value of RMB8 million. NCC’s R&D has come up to the same international advanced level as laboratories of some leading chemical companies as BASF, Ashland and Akzo Nobel.

Hydrolyzed Polymaleic Anhydride (HPMA)

CAS NO: 26099-09-02  

Other Names: HPMA; Hydrolyzed Polymaleic Anhydride; poly(maleicacid);Polymaleic Acid; MALEIC ACID POLYMER;Polymaleic Acid

Structural Formula:

Properties:

1)     HPMA is a low molecular weight polymeride, with average molecular weight 400-800.

2)     No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature

        above 330°C.

3)     Has obvious threshold effect under high temperature (350°C) and high pH(8.3)level, suitable

        to be used in alkaline water system or built with agents.

4)     It has good scale inhibition against carbonate and phosphate scales under temperature

        300°C with effective time as long as 100 hours.

Specification:  GB/T 10535-2014

Application range:

1)     Due to its good scale inhibition and high temperature tolerance properties, 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.

2)     In addition, has good corrosion inhibition effect when used together with zinc salt.

3)     Can also used as additives for cement.

Using Method:

1)      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.

2)     HPMA has good scale inhibition (98%) and scale stripping properties. When used together

        with zinc salts, it can effectively inhibit carbon steel corrosion.

Safety:

       Acidity. Avoid contact with eye and skin. In case of contact, flush with water immediately.

Package and storage:

1)  25kg/250kg net in plastic drum, or as required.

2)  Storage for twelve months in shady and dry place.
