Nanometer SiO2 is small, narrow size distribution, micropore more than the large surface area and high content of surface hydroxyl groups, ultraviolet, visible and infra-red reflective ability and so on. By IR spectroscopy, nano-silica surface of a large number of hydroxyl and unsaturated residue key, and deviate from the steady-state silicon-oxygen structure. Test analysis by the BET method, nano-silica large specific surface area.
Synonyms: Nanometer silica Formula: SiO2, Mol. Wt.: 60.08. Molecular Formula: SiO2; Molecular Weight: 60.08
CAS No.: 14808-60-7
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. Other industries It can be also used in electronic encapsulation, polymer of macromolecule, paint, adhesive, functional fiber, cosmetics and many more applications.
