POLYASPARTIC ACID - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| application | polyaspartic acid is a green chemical with excellent performance and biodegradability. it not only has good calcium ion exchange ability and biodegradability, but also can destroy calcium salt crystal scaling. it can be used as a water quality stabilizer for industrial circulating cooling water. |
| reaction mechanism | using ammonium carbonate and maleic anhydride as raw materials, the average molecular weight of the synthesized polyaspartic acid is 3000~6000 by indirect polymerization, which meets the requirements of using as a circulating cooling water scale inhibitor. |
