Sodium tripoliphosphate
TU 2148-095-43499406-98
Sodium tripoliphosphate (Na5P3O10) is used as a raw material for the production of synthetic detergents, production process of ceramic tiles, treatment of water for the feeding of boilers, in the meat and diary industry, and for a great number of other applications.
In terms of physical-chemical properties sodium trypolyphosphate must meet the following standards:

Sodium tripolyphosphate is packed in valve bags or open four, five, six-layer paper bags according to GOST 2226 brand BM, polyethylene bags, as well as in bags from polypropylene or analogous materials with analogous firmness characteristics according to respective regulatory documents. Net weight of the bag with a product - 50+/-1 kg Transportation in “BIG BAG” type soft special containers for powdery products, also in specially equipped covered wagons or in bulk is permissible. Sodium tripolyphosphate is stored in closed warehousing premises or under a shelter. The product storage time is indefinite.
