Spherical Silica Powder Description
Spherical Silica Powder (SiO₂) is a highly uniform, spherical silicon dioxide material. Compared to irregular silica powders, its spherical particles offer superior performance in flowability, dispersion, and consistency. The powder typically has high purity, a narrow particle size distribution, and excellent whiteness.
Key benefits include:
- Uniform Particle Shape: Consistent spheres ensure reliable performance.
- Excellent Flowability: Smooth handling in coatings, inks, cosmetics, plastics, and composites.
- Enhanced Stability: Improves durability and performance in final products.
Spherical Silica Powder Applications
- Coatings & Inks: Enhances surface smoothness, gloss, and consistency.
- Cosmetics: Improves texture, opacity, and application uniformity in powders and creams.
- High-Performance Rubber & Plastics: Acts as a filler to improve mechanical properties and processing efficiency.
- Electronics & Composites: Provides insulation, dimensional stability, or uniform filler distribution.
Spherical Silica Powder Packing
- Supplied in sealed, labeled containers to protect quality during storage and transportation.
- Custom packaging options are available for large-volume orders.
