Seven proven anatase grades — fibre first
Delustering pigments for polyester, acrylic and viscose, in-polymer grades for nylon, a general-purpose anatase for plastics, paper, rubber and coatings, HK-400 food-contact grade for food and pharmaceutical applications, and HK-500 food-grade anatase for cellulose acetate fibre. Every grade carries a full datasheet — and we will help you match one to your process.

Fibre-Grade Anatase TiO2 - Delustering Pigments
For filament and staple fibre spinning across polyester, acrylic and viscose. Semi-dull and full-dull loading, low 45 µm residue to protect spinnerets.
HK-600 is an anatase titanium dioxide for polyester fibre, ultra-fine ground and inorganically surface-treated with additives. Uniform particle size, high retention and low dosage make it a dependable delustering pigment for filament and staple fibre.
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.
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.
Nylon & In-Polymer Masterbatch Grades
Coated anatase engineered for polyamide polymerisation temperatures, where dispersion stability and thermal colour fastness decide the outcome.
General-Purpose Anatase for Plastics, Coatings & Paper
A dependable workhorse grade where whiteness, brightness and cost-in-use matter most.
High-Purity Grades (Food & Pharmaceutical)
Food- and pharma-grade anatase from the group's phase-II plant in Huai'an. HK-400 (food and pharmaceutical colouring) and HK-500 (cellulose acetate fibre) are the published food-contact grades; other high-purity specifications are available on request. Hontai Global handles export documentation, sampling and logistics.
HK-400 is a food-contact anatase titanium dioxide for food and pharmaceutical applications: high whiteness and hiding power, excellent dispersibility and chemical inertness, and low heavy-metal content.
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.
