Calcined Kaolin

[product name]: HS-901B Ultra Fine & Super White calcined kaolin

[Character and Performance]:

The crystal is in laminar structure of pseudo-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 for improving its performance;
The coating containing HS-901B has good performance in water-preserving, fluidity, viscosity. It can improve the property of paper such as whiteness, smoothness, opacity, ink absorbency, printability and luster, especially the whiteness and ink absorbency.

[Application]:

Medium-quality paper-making such as thermal sensitive paper, decorating paper, coated paper and paper board, etc.
