CAS No.:7758-29-4 EINECS NO.:7758-29-4 Product Sodium Tripolyphosphate(STPP) Density 2.52 Melting point 622 Insoluble Organic solvent Soluble In water Molecular Weight 367.86 PH(1% aqueous solution) 9.2-10 Executive Standard GB/T 9983-2004 Pallet Based on buyer's requirment Shelf life 2 Years Proper Storage Product details 1. Apparent density 0.35-0.9g/cm3, melting point 622oC, can be soluble in water. 2. Alkaline aquesous solution, 1% aqueous solution of PH 9.7. 3. Can gradually be hydrolysed in the water into subphosphate, has a good ability to compelex metal ions. 4. Can form soluble complexes with calcium, magnesium, iron and other metal ions. 5. Can soften hard water, As an inorganic surface active, but also organin surface active agent. Be used for Industrial grade Sodium Hexametaphosphate(STPP) Application: 1. Sodium tripolyphosphate is used for meat processing, synthetic detergent formulations, textile dyeing, also used as dispersing agent, solvent etc. 2. It is used as soft water, also used in confectionery industry. 3. It is used as power stations, locomotive vehicle, boiler and a fertilizer plant cooling water treatment, water softener. It has strong ability to Ca2+ collaterals, per 100g to complex 19.5g calcium , and because SHMP chelation and adsorption dispersion destroyed the normal process of calcium phosphate crystal growth, it prevents the formation of calcium phosphate scale. Dosage is 0.5 mg/L, prevent that scaling rate is up to 95%~100%. 4. Modifier; emulsifier; buffer; chelating agent; stabilizer. Mainly for canned ham tenderization; canned broad beans in the Yuba softening. Can also be used as soft water, pH regulator and thickening agent. 5. It is used for synergist for soap and preventing bar soap grease precip.
