Key features

High Purity Industrial Grade: 94.0% minimum purity with ISO certification for industrial applications.

Effective Water Softening: Reacts with Ca2+, Mg2+, Fe3+ ions to soften hard water in detergents.

Anti-Caking Performance: Absorbs moisture to become hexahydrate, keeping powder dry and free-flowing.

Versatile Industrial Use: Used in detergent, food, paper, oil drilling, ceramics, and water treatment.

Buffering Agent: Maintains detergent solution pH at 9-9.5 for effective acid dirt removal.

Enhanced Cleaning Power: Improves emulsifying and dispersing power to solubilize protein and dust.

Long Shelf Life: Real shelf life exceeds 2 years if stored in sealed, dry, and cool conditions.

Global Supply Chain: Over 60% of China's STPP exports with stable global supply chains.

Product Q&A

Q:What is the purity and certification of this STPP?

The product is Industrial Grade with a minimum purity of 94.0% Na5P3O10 and holds ISO certification.

Q:What are the main applications of Sodium Tripolyphosphate?

It is primarily used as a water softener and buffering agent in the detergent industry, and also serves as a quality modifier in food, paper making, oil drilling, and water treatment.

Q:How does STPP function in detergent systems?

It softens hard water by reacting with metal ions, enhances emulsifying power, acts as a buffering agent to maintain pH 9-9.5, and prevents caking by absorbing moisture.

Q:What is the difference between Phase I and Phase II STPP?

They have the same chemical properties but different crystal structures. Phase I hydrates faster, releases more heat, and is more prone to caking during dissolution compared to Phase II.

Q:What is the actual shelf life of the product?

While the COA lists 2 years, the real shelf life is much longer if stored properly in sealed bags, away from sunlight, moisture, and incompatible chemicals.
