Product Description

product information:

Spherical silica powder

Spherical silica micro-powder is a high-purity and ultra-fine spherical silicon dioxide (SiO) powder, processed through special techniques, and has excellent physical and chemical properties. Its spherical particle morphology endows it with characteristics such as high fluidity, low stress, and high filling rate, and it is widely applied in fields such as electronic packaging, composite materials, coatings, adhesives, and ceramics.
 

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.
