The Use of Nanometer SiO2 (rubber)

Nanometer SiO2 (rubber) occurs as a white powder.
Nanometer silicon dioxide (Nm-SiO2) is a new kind of inorganic materials, because of its
extra small size. It has many special characteristics, such as big surface volume, quanta
tunnel, and so on. Storage: in cold, dry and airtight environment, avoid exposing to
volatile substances.
The mechanical intensity of pure rubber is very low. But rubber’s tensile strength will
be increase from 0.35MPa to 14MPa after adding some wanjing nanometer silicon dioxide.The
rate of tensile strength increases more than 40 times ,but other rubbers can increase
1.4-10 times only. Product name: Nanometer silicon dioxide CAS No.: 14808-60-7 Synonyms:
Nanometer silica Formula: SiO2; Chemical structure: O==SI==O Mol. Wt.: 60.08; ITEM Nm-
SiO2 Powder Nm-SiO2 Solution Nm-SiO2 Alcohol solution Nm-SiO2 slurry
It is mainly used in:
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.Other industries: used in electronic encapsulation, polymer of macromolecule, paint,
adhesive, functional fiber, cosmetics and many more applications.
5.Coating: Using nm-SiO2 in coating can improve the suspend stability, thixotropic,
weatherability, anti-washing and anti-infra-red.
