For our product, Bulk density between 0.5-0.75 were present granular looking, it always used on ceramic products. After smash, it becomes powder and density were between 0.7-0.95 and we call it ‘high density’ mostly. As Phase I, detergent industry always need lower index like 20-30 cause the lower Phase I were be better in thermostabilization and its Hydration speed of their final product.

Product Application

Industrial grade

STPP can used as detergent additive, and also can use in petroleum, metallurgy, mining, paper making, water treatment, etc. What’s more,it is mainly used as an assistant of synthetic detergent, as a soap synergist and to prevent soap grease from separating out and blooming.

Sodium Tripolyphosphate

Food grade

Sodium tripolyphosphate is used to solidify raw ham. 2 kg of No. 3 mixed salt (refined salt 91.65%, granulated sugar 8%, sodium nitrite 0.35%) and 85 g of sodium tripolyphosphate were added to every 100 kg of meat, which were fully stirred and solidified at 0-4 refrigerated temperature for 48-72 hours. By the way, it can soften the skin of canned broad beans. Many fruits and vegetables have tough skin. As fruits and vegetables mature, the skin becomes more and more tough. Calcium can be complexed by adding polyphosphate to blanching or soaking water for fruit and vegetable processing, thereby reducing skin toughness.
