Active Poly Sodium Metasilicate

Item : APSM

Details :

APSM is a spray-dried powder or granule (density 0.2-0.55g/ml) that is comprised of β-type sodium silicate crystals, amorphous sodium silicate and auxiliary agents. It is intended for use as 4A zeolite or STPP surrogate in non-phosphorus detergent products.

Characteristics:

1. The Ca/Mg sequestrability of APSM is higher than 4A zeolite and equivalent to STPP. That results in faster water softening
2. APSM has good compatibility with detergent agents, particularly non-ionic surfactants. It has moderate detergency when used individually.

3.Excellent water solubility (>15g/100ml).

4. Excellent penetrating, emulsifying, suspending, anti-settling and pH buffering properties.

5. High whiteness
6. APSM can significantly improve fluidity of stock liquid (pre-drying) and allow higher solid content, thus reduce energy cost.
7. Ideal surrogate for 4A zeolite.
