Most suppliers give you “good enough”. We give you the spec sheet your R&D team dreams about:
| Key Property | Our Value | Why It Matters for You |
|---|---|---|

| Median Particle Size (D50) | 1.48 µm | Silky feel in coatings, flawless dispersion in plastics |
| D90 | 6.59 µm | No oversized particles to ruin surface finish |
| Top Cut (d97.48%) | 10.48 µm | Perfect for high-gloss paints & thin films |
| Particles < 2 µm | 58.04% | Exceptional opacity and reinforcement |
| Whiteness (ISO) | 95.5% | Your white just got whiter — no TiO₂ cheating |
| L*/a*/b* | 96.5 / 0.2 / 0.54 | Almost pure white, tiny yellow cast |
| Oil Absorption | 37 g/100g | Lower resin demand = real cost savings |
| Moisture | 0.2% max | No clumping, no production stops |
| pH | 9 | Safe for every polymer and coating system |
| Density (M/V) | 2.7 g/cm³ | Standard and predictable |
