High purity spherical silica powder

Product parameter

Product introduction:
Our company has successfully developed spherical SiO2 micro powder with high spherical rate and high purity. The particle size and distribution can be adjustable. Now it has gradually replaced the imported products and the technology has been patented. 
The product has been successfully applied to EMC, CCL and other fields as filling material, which can greatly improve the rigidity, wear resistance, weather resistance, impact resistance, tension resistance, fire resistance, arc insulation resistance and ultraviolet radiation resistance of electronic products.
