Note: We can supply different size products of silica powder according to client's requirements.

Nano-silica has small particle size and high reactivity, and the bulk density of powder is relatively small and easy to disperse;


Application of Amorphous silica powder

1. Rubber modification, sealant ceramic toughening, binder modification, functional fiber additive, plastic modification, anti-paint aging additive, ceramic, nano ceramic, composite ceramic substrate;
2. Flame retardant materials, coatings, advanced grinding media, can increase the thermal stability and aging resistance of the polymer;
3. Adding a small amount of nano-silica in traditional coatings, it solves the problems of poor suspension stability, poor thixotropy, poor aging resistance and low finish.



SEM & XRD of Amorphous silica powder:

Amorphous silica powder


Storage conditions:
Amorphous silica powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
