Silica (chemical formula: SiO2) is an acidic oxide, and the corresponding hydrate is silicic acid (H2SiO3). Silica is the most important compound of silicon. The natural silica present on the earth accounts for about 12% of the mass of the earth's crust. Its existence is crystalline and amorphous. It is collectively called silica.

Function:

Application Area:
1.Rubber modified, sealant ceramic toughening modification, adhesives, functional fiber additive, plastic modification, paint aging additives;
2.Ceramics, nano ceramic, composite ceramic substrate;
3.Polymer: can increase the thermal stability and anti-aging polymer;
4.Flame retardant materials and coatings, high grinding medium, cosmetic products;
5.In cluster butyl benzene and chlorinated polyethylene adding a small amount of nano SiO2produce color rubber tenacity, elongation, strength, flexural performance and ultraviolet resistance and thermal aging performance and achieve or exceed epdm;
6.In traditional coating adding a small amount of nano silicon oxides, good solve the suspension stability, thixotropy and poor, poor finish.
