Applications: |
|
Calcined Kaolin for Paper Industry: Our Grades are preferred as raw material to manufacture paper for coating and as a filler to reduce consumption of costlier wood pulp, it give brightness, smoothness & better printing.
Calcined kaolin for paint Industry: Our Grades are used in satin and matt paints where they can deliver increased opacity, whiteness and scrub resistance. Calcined Kaolin is particularly useful as a partial replacement for TiO2 pigment.
Calcined Kaolin for Coating Industry: Our Grades are used to improve the mechanical properties such as the moisture resistance, impact resilience of the paint, the floatation resistance capacity of the pigment all can be improved.
Calcined Kaolin for Ink & Adhesives Industry: our grades can be applied to ink formulation as trophoplasm pigment because of the strong chemical inertness and almost without impurity and soluble salt
Calcined Kaolin for PVC Cables & Wires Industry: our grades are used in the industry to improve electrical properties and as a functional additive material.
Calcined Kaolin for Ceramic Industry: Our grades are used to achieve strength, low iron and titanium to avoid color variation, and better shaping.
Calcined Kaolin for Rubber Industry: Our Grades are adds strength, abrasion resistance and rigidity to rubber.
Calcined Kaolin for Plastic Industry: Our Grades are used to achieve smooth surface, dimension stability, low shrinkage and cracking during compounding & forming. |
