Introduction of spherical SiO2:
Spherical quartz powder has excellent properties such as a smooth surface, large specific surface area, high hardness, and stable chemical properties. First of all, the spherical powder has good fluidity, the resin is stirred evenly to form a film, the resin addition is small, the quartz powder filling amount is high, and the mass fraction can reach 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, the smaller the thermal expansion coefficient of plastic sealing materials, the closer to the thermal expansion coefficient of single crystal silicon, the better the performance of the produced electronic components.
Secondly, the stress of spherical powder is only 60% of that of angular powder, and the plastic sealing material made of spherical quartz powder has the lowest stress concentration and the highest strength. Finally, the spherical powder surface is smooth, the friction coefficient is small, the mold wear is small, and the mold life can be extended by more than one time.

We are a trusted global supplier of spherical silica quartz oxide. Please feel free to send inquiries about the latest price of spherical quartz powder.

Properties of spherical quartz powder
1. High sphericity, uniform particle size, large additive volume, and insignificant change in viscosity of polymer system;
2. good surface fluidity of spherical silicon oxide, stirring with resin to form a uniform film, small resin addition, good fluidity, and high powder filling. The smaller the coefficient of thermal expansion, the lower the thermal conductivity; the closer to the coefficient of thermal expansion of single crystal silicon, the better the performance of the electronic components produced;
3. When spherical silicon oxide-filled plastic encapsulates IC chips, the yield is high, the friction coefficient of spherical silicon oxide powder is small, and the mold wear is small, making the mold service life long. Compared with the corner powder, the mold can be improved. The service life is doubled;

Application of spherical quartz powder
Spherical SiO2 is mainly used in high-temperature vulcanized silicone rubber, silicone defoamer, advanced ink, powder coating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, sheet preparation, cosmetics, etc.
Spherical silica powder not only has a good shape but also has high chemical purity and low content of radioactive elements, which can meet various technical requirements in high-end integrated circuits, and its application can greatly reduce the thermal expansion coefficient of packaging materials, reduce the dielectric constant, reduce stress, greatly enhance the rigidity and wear resistance, weather resistance, impact resistance, compressive strength, tensile strength, wave resistance, flame resistance, so that the products have good arc resistance insulation It has become an indispensable key electronic packaging material.
Spherical quartz powder is mainly used in the field of electronic packaging but is also widely used in electronic ink, optical fiber, high-end cosmetics, advanced precision ceramics, optical devices, and electronic components precision grinding and used as filler for special paints and coatings.

Besides spherical quartz powder, we also have the below popular products.
