Technical data sheet
HK-800 Fibre-Grade Anatase TiO₂ for Acrylic & Viscose
HK-800 is an anatase titanium dioxide for demanding fibre lines such as acrylic and viscose. Inorganic aluminium coating plus organic treatment delivers superior dispersibility and filterability.
Fibre Grade (Acrylic & Viscose)
≤ 0.01 %Sieve Residue on 45 µm
≥ 99Whiteness
≥ 97 %TiO₂ Content
Key benefits
- Ultra-low residue (≤ 0.01 %) for longest spinneret life
- Whiteness ≥ 99 for a brighter, cleaner fibre white
- Inorganic Al coating for superior dispersion stability
- Ideal for acrylic and viscose spinning systems
