[product name]HS-901B calcined kaolin/Ultra Fine& Super White calcined kaolin
[Character and Performance]
The crystal is in laminar structure ofpseudo-hexagonal kaolinite platelets.
Super fine particle with narrow distribution,little residue on 325 mesh, and low abrasion;
Great whiteness, covering power, light dispersion,fluidity and viscosity;
Excellent extender of titanium dioxide forimproving its performance;
The coating containing HS-901B has good performancein water-preserving, fluidity, viscosity. It can improve theproperty of paper such as whiteness, smoothness, opacity, inkabsorbency, printability and luster, especially the whiteness andink absorbency.
[Application]
Medium-quality paper-making such as thermalsensitive paper, decorating paper, coated paper and paper board,etc.
