Sokalan PA 15 is a sodium polyacrylate salt. This product is miscible with water in any proportion (including seawater), and also soluble in mixtures of water and water-soluble solvents. It features low residual monomers and stable physical properties. The product is non-toxic and has been certified by KIWA-ATA and NSF (USA). It disperses microcrystals or sediments of salts such as calcium carbonate, calcium phosphate, and calcium sulfate in water without precipitation, controlling scale formation in desalination devices and keeping membrane fouling in a free state, thereby achieving scale inhibition. When compounded with organic phosphonates, organic phosphonate esters, and polyphosphates, it exhibits good synergistic effects and can operate under alkaline and high concentration multiple conditions without scaling. This product has low acute toxicity, is non-irritating, and shows no sensitization tendency. According to EU chemical regulations, it is classified as a non-hazardous substance. It is not highly toxic to marine life, and the discharge of concentrated water after desalination does not pollute the environment.
