Key Features
High Purity: The content of SiO2 is ≥99.6%, and the impurity content is extremely low. Spherical Particles: Smooth surface, good fluidity, and reduce mechanical wear. Controllable Particle Size: The average particle size ranges from 0.1μm to 50μm, and it can be customized according to requirements. Low Coefficient of Thermal Expansion: Improve the thermal stability of materials. High Insulation: Suitable for scenarios with high insulation requirements such as electronic packaging. Chemical Inertness: Resistant to acid and alkali corrosion, with strong stability.
Resistant to acids, alkalis, and corrosion, compatible with most resin and plastic systems, extending end-product lifespan.
Product Application
Electronic Packaging: Chip packaging, epoxy resin filler, PCB substrate. Composite Materials: Enhance the performance of materials such as plastics, rubbers, and ceramics. Coatings & Adhesives: Improve wear resistance, weather resistance, and leveling property. 3D Printing: Serve as a high-performance filler for additive manufacturing. Cosmetics & Medicine: Used as a functional additive to improve product texture.
Customization Service Customizable particle size distribution and surface treatments (e.g., hydrophobic modification) for diverse industrial applications.
