Paper (GB-CK98 and GB-CK98L are recommended)

Calcined kaolin is mainly used as coating and filler pigment in papermaking to improve the brightness, smoothness and printing performance of paper; also to increase the opacity of it. Calcined kaolin is strong in covering and high in brightness due to its sheet structure. Meanwhile, calcined kaolin makes the coating having excellent bulk density and printing applicability due to its special porosity structure. Thus, the paper has better ink injection and it can obviously improve the printing performance. Calcined kaolin used in papermaking usually has higher requirement in the particle size, brightness, oil absorbency and bulk density.
