Application of Silicon Dioxide

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.

 

Characteristics of Silicon Dioxide:

1) White dispersed powder

2) Can be dissolved by NaOH and HF, but cannot be dissolved by other kinds of acid, water and solvents

3) It has a good performance

4) With resistance to higher temperature

5) Will not combust and has good isolation
