Copolymer of Maleic and Acrylic Acid (MA/AA) CAS NO.26677-99-6

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.

Copolymer of Maleic and Acrylic Acid (MA/AA)

CAS NO:  26677-99-6

Other Names:  Maleic-methyl acrylate copolymer

Structural Formula:

Properties:

MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate and scale inhibition for water scale like phosphate. It has good thermal stability, and can be used under high temperature (300℃). MA/AA has good compatibility when used together with other agents. Due to its good scale inhibition and high temperature tolerance properties，MA/AA is widely used in low-pressure boiler, centralized heating, centralized air-conditioner and circulating cool water system. It can also be used as chelating dispersants in woven and dyeing fields.

Specification: HG/T 2229-2009

Usage:

MA/AA is used in circulating cool water system, medium or lower pressure boiler and distillation system in which high temperature is usually encountered. MA/AA can be used alone or together with other organic phosphates. When used together, the dosage of 2-10mg/L is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments.

Safety:

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

Package and Storage:

Normally 25 kg or 200kg net in drum. Storage for one year in shady room and dry places.
