Nanometer silica powder (nm-SiO₂) is a new kind of inorganic materials, because of its extra small size (1 to 100 nanometer). It has many special characteristics; such as big surface volume, quanta tunnel, and so on. So all such properties makes it different from other materials. It can be widely used in electronic encapsulation, polymer of macromolecule, rubber, plastics, coating, paint, adhesive, functional fiber, cosmetics and many more applications.

Its main capabilities as following:

SiO₂%（wt,dry）                                               ≥97.0%；

Particle size（nm）                                             ≤30

Specific surface area（m²/g）                          ≥200

Free moisture（110℃,2h,wt）                           ≤5%

Loss on Ignition（900℃,2h,wt）               ≤2%

Rocking density(g/cm³)                           ≤0.07

According to different application industries and application environment, the company can provide hydrophilicity and oil-friendly nano-silica powder.
