Main advantages of our calcined kaolin:
It is characterized by good flow, high plasticity, whiteness, fine particle size, bright luster, opacity, pure white, kaolin soft, easily suspended in the water,high cohesiveness, excellent electrical insulating properties,good acid soluble and very low resistance.
Application:
1) In ceramics producing
2) In paints and coatings as the materials
3) In oil-based paints and plastics
4) In rubber mixture
5) In papermaking to improve its whiteness
