Technical data sheet
HK-500 Food-Grade Anatase for Cellulose Acetate
HK-500 is a food-grade anatase titanium dioxide for cellulose acetate fibre: a single-aluminium inorganic surface treatment gives excellent dispersibility and filterability, with controlled heavy metals.
Food-Grade (Cellulose Acetate)
≥ 98 %TiO₂ Content
≤ 3 ppmArsenic (As)
≤ 10 ppmLead (Pb)
Key benefits
- Food-grade standard: arsenic (As) ≤ 3 ppm, lead (Pb) ≤ 10 ppm
- Single-aluminium inorganic coating for excellent dispersibility and filterability
- High whiteness: L* ≥ 98, b* ≤ 1
- Engineered for cellulose acetate fibre colouring
- Standard 25 kg bags
