HK-700 Fibre-Grade Anatase TiO₂ for Polyester & Masterbatch
HK-700 is an anatase titanium dioxide for chemical fibre spinning. Water-based organic treatment gives excellent dispersibility and filterability — engineered for demanding spinning lines.
Fibre Grade (Chemical Fibre Spinning)
Key benefits
- Excellent dispersibility for spinning applications
- Low 45 µm residue (≤ 0.03 %) protects spinnerets
- Stable whiteness and tinting strength
- Proven in polyester fibre and masterbatch production
