Titanium dioxide applications across fibre, plastics & coatings
Anatase TiO₂ brightens and protects the materials you make. Whatever your process, we help you match grade performance to application requirements — with data, not guesswork.
Recommended grades by application
Nylon & polyamide masterbatch
Nylon polymerisation runs hot — standard pigments agglomerate and yellow. HK-900's inorganic Si-Al coating stays dispersed and stable through polymerisation, keeping fibre lustre and spinning reliable.
Recommended: HK-900
Paper, rubber, coatings & ink
General-purpose anatase for filler and pigment uses — remarkable whiteness, coverage and dispersibility at a dependable price with stable logistics from Hong Kong.
Recommended: HK-200
Food contact & pharmaceutical
HK-400 is a high-purity anatase for colouring food and pharmaceutical products — high whiteness and chemical inertness with controlled heavy metals (arsenic ≤ 3 ppm, lead ≤ 10 ppm).
Recommended: HK-400
Cellulose acetate fibre
Cellulose acetate spinning needs a pigment that disperses cleanly and never blinds the spinneret. HK-500 is a food-grade anatase with single-aluminium inorganic treatment — excellent dispersibility and filterability, with controlled heavy metals (arsenic ≤ 3 ppm, lead ≤ 10 ppm).
Recommended: HK-500

●●● Highly recommended · ●●○ Suitable · — Not typically specified. HK-600 and HK-700 are specified for polyester filament and staple, and HK-700 is also our lead grade for polyester masterbatch. HK-800 is the premium choice for acrylic and viscose, and its ultra-low 45 µm residue also suits high-loading full-dull polyester. HK-200 covers coatings, paper, rubber, plastics and general-purpose fibre applications, HK-400 is the food-contact grade for food and pharmaceutical colouring, and HK-500 is the food-grade anatase specified for cellulose acetate fibre.
