Calcined Kaolin for Paper/Painting/Ink (GRCK-40/GRCK-50/GRCK-60)

4000 mesh /5000 mesh/6000 mesh calcined kaolin for paper/painting/ink/cosmetics

Typical Physical and Chemical Properties

Under calcined kaolin made by coal gangue and aluminous rocks. After the calcined modified, they are high brightness and good chemical stability, can be widely used in paint and coating, papermaking, rubber, plastic, cable, ceramics and other fields.
Fetures: Pure and high brightness, fine grain and low screen residue, ecentralized and well covering performance and floating, not easy replace lithphone and partly of titanium dioxide to lower the product cost.

Applications:
GRCK-40, GRCK-50 Applied for Copperplate paper and White version of paper, foam rubber painting, ink and cosmetics, partly takes place of the titanium dioxide
GRCK-60 Used in rubber and ink.
