High Filling Performance
The spherical structure makes the accumulation between particles tighter. The filling amount can reach 60-80% (volume ratio), effectively reducing the material cost.
Even under high filling levels, it still maintains excellent fluidity, reducing processing energy consumption and equipment wear.
Low Friction Coefficient
With a smooth surface, the friction coefficient is ≤ 0.15 (more than 30% lower compared with traditional irregular silica powder), which can reduce the internal friction of the material and improve the demoulding performance.
It is suitable for friction-sensitive components (such as gears, bearings, etc.), prolonging the service life of products.
Excellent Physical Properties
It has high purity (SiO₂ ≥ 99.5%), strong chemical stability, and excellent acid and alkali resistance.
The sphericity is ≥ 98%, the particle size distribution is uniform (D50: 1-100μm is optional), the specific surface area is small, and the oil absorption is low.
Enhanced Performance of Composite Materials
It improves the rigidity, compressive strength, and impact resistance of materials, while reducing the shrinkage rate and warpage deformation.
It improves the thermal conductivity and electrical insulation properties, meeting the high-performance requirements of the electronics, automotive, and other fields.
