Product Description

 
Product name: Sodium tripolyphosphate; STPP inudstry grade; Sodium Tripolyphosphate tech grade.
CAS No. :7758-29-4
Molecular formula:Na₅O₁₀P₃
Quality standard: GB/T9983-2004

Description:

Sodium tripolyphosphate is white granular or powder, apparent density 0.35-0.95g/cm3, melting point 622 ºC. It is easily soluble in water and the aqueous solution is alkaline. In the water salt has good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. It can soften hard water surfactant and has certain properties of organic surfactant.

Application: 
We all use genuine raw materials to produce industrial grade sodium tripolyphosphate with less impurities and low content of heavy metals. It can be used as additives for synthetic detergent, industrial water softener, boiler water softener, drilling mud dispersant, stain agent, soap synergist and preventing soap grease precipitation and frosting.

Packing: 25kg or 50kg plastic bag, 1000kg jumbo bag. Or agree on the packaging method according to the user's needs.
