High-purity silicon powder can be used in plastics to effectively add the bending and compressive strength of plastics, and it can also improve the bearing capacity of most plastic products; it can replace carbon black in rubber products and improve the elongation and tensile strength of rubber. Tear strength and anti-aging function.

As a coating additive, it can significantly improve the wear resistance of the coating and enhance its coloring ability. But its market prospect is to be used in the fields of plastic packaging materials for large-scale and very large-scale integrated circuits, electronic components plastic packaging materials, epoxy castable potting materials and other fields.

In epoxy molding encapsulation, high-purity silicon powder is the main raw material. Because SiO2 has stable physical and chemical functions, outstanding light transmittance, linear expansion and excellent high-temperature functions, SiO2 is the current epoxy molding compound. Filling materials, the filling rate can reach 70%~90%, and high-purity ultra-fine silicon powder is also a semiconductor integrated circuit substrate material.

The international demand for high-purity ultra-pure silicon powder will follow the development of the IC industry and develop rapidly. It is estimated that the international demand for it will increase at a rate of 20% in the next 10 years.

The above are the main uses of different grades of high-purity silica powder briefly described by the editor. Let's understand it briefly. The content is for reference only. If you want to know more about silica powder, you can always pay attention to our website update.
