HK-600 Fibre-Grade Anatase TiO₂ for Polyester
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.
Fibre Grade (Polyester Polymerisation)
Key benefits
- Uniform particle-size distribution for consistent light scattering
- High retention and lower dosage per tonne of polymer
- Developed for polyester filament and staple fibre delustering
- Inorganic surface treatment with additives for slurry stability
