Properties
White powder or white granules, relative density 1.86, soluble in water, insoluble in ethanol. The aqueous solution hydrolyzes to phosphoric acid when heated with dilute inorganic acids. It is hygroscopic and forms a hexahydrate after absorbing water. When heated above 220°C, it decomposes to form sodium metaphosphate.

Packaging
The regular packaging is a 25KG bag, with a double-layer plastic inner bag and a plastic woven outer bag. It can also be packed in 1000/1100/1200KG ton bags.
Customized packaging and shipping marks are available.
