Technical data sheet
HK-900 Nylon-Grade Anatase TiO₂
HK-900 is an anatase titanium dioxide for nylon polymerisation. Inorganic Si-Al coating with organic treatment gives outstanding dispersibility and thermal stability at polymer processing temperatures.
Nylon Grade (In-Polymer)
≥ 8000 Ω·cmSpecific Resistivity
≤ 0.01 %Sieve Residue on 45 µm
≥ 96 %TiO₂ Content
Key benefits
- Engineered for nylon polymerisation temperatures
- Si-Al coating prevents agglomeration in polyamide
- Outstanding thermal stability and colour protection
- Ultra-low residue (≤ 0.01 %) for clean filters
