Detailed Description

Sodium Tripolyphosphate(STPP) Byname: Pent-sodium Phosphate Molecular formula: Na5P3O10 Molecular Weight: 367.86 Sodium Tripolyphosphate(STPP) CAS Number: 7758-29-4 Sodium Tripolyphosphate(STPP) Properties: White powder; Melting point 622° C; Easily soluble in water; Sodium Tripolyphosphate(STPP) has got salient chelating capacity to ions of Ca and Mg etc. And can soften hard water to make suspension solution become into clear solution; Sodium Tripolyphosphate(STPP) Has got weak alkalinity but no corrosiveness. Sodium Tripolyphosphate(STPP) is a surfactant, and has got outstanding emulsification to lubricants and fat. Sodium Tripolyphosphate(STPP) has different bulk density, I. E. Low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. This product has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving. Sodium Tripolyphosphate(STPP) Sodium Tripolyphosphate(STPP) Uses: Used as one of the main auxiliaries for synthetic detergent, synergist for soap; Water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.; As an oil contamination resistance agent in paper production. In foodstuff industry Sodium Tripolyphosphate(STPP) is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. Sodium Tripolyphosphate(STPP) may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. Sodium Tripolyphosphate(STPP) may also serves as a softener or densifier in foodstuff industry. Sodium Tripolyphosphate(STPP) Packing and storage: In 25Kg, 50 Kg, 1000 Kg bage. Store at a cool, dry and well ventileated place.
