Application:

1. Rubber: Nm-SiO2 can be used in re-attrite rubber for it can improve the functions of rubber such as intensity, tenacity, anti-aging, re-attrite and so on. It also can be used in transparent pastern of sole.

2. Plastic: Nm-SiO2 can improved the intensity, tenacity and anti-aging capabilities of plastic. Adding nm-SiO2 into organic glass (PMMA) can improve PMMA's intensity, impactive tenacity, attrited resistance, transparence, anti-ultraviolet and anti-aging capabilities.

3. Epoxy resin :Its rigidity, intensity, tenacity, high temperature resistance and anti-aging capabilities can be improved after being modified by nm-SiO2.

4. Coating: Using nm-SiO2 in coating can improve its suspend stability, thixotropic, weatherability, anti-washing and anti-infra-red.

5. Gooey and sealant: Adding nm-SiO2 into gooey or sealant can improve the ropy of gooey and the sealed ability of sealant.

6. Other industries It can be also used in electronic encapsulation, polymer of macromolecule, paint, adhesive, functional fiber, cosmetics and many more applications.
