Can it replace STPP completely?

It cannot completely replace STPP because STPP has unique features like enhancing emulsifying power and acting as an anti-caking agent by absorbing moisture to keep powder free-flowing.

What are the available forms and specifications?

It is available as white granular or fine powder with bulk densities of 0.35-0.45 g/cm3 (granular) and 0.48-0.60 g/cm3 (fine), and whiteness of 85% min.

Product Q&A

Q:What is the main application of this product?

It is primarily used in the detergent industry to replace STPP (Sodium Tripolyphosphate) in detergent powder formulations, offering a lower cost and zero phosphorus pollution.

Q:How does it compare to STPP and Zeolite?

It offers higher Ca2+ exchange capacity (550 mg/g) than Zeolite (295 mg/g) and STPP (158 mg/g), while being more cost-effective than STPP and environmentally safer than phosphorus-based alternatives.

Q:What are the key chemical properties?

It has a purity of 95% min, SiO2 content of 25% min, pH value of 12.5 max, and strong pH buffering ability with good water softening performance.

Q:Is it suitable for low-temperature washing?

Yes, it exhibits good performance in low-temperature water and maintains strong cleaning capabilities even under such conditions.

Q:What is the shelf life of the product?

The COA typically lists a shelf life of 2 years, but the actual shelf life is much longer if stored in sealed bags away from direct sunlight, moisture, and incompatible chemicals.
