Kaolinite-An essential component of performance mineral industry

Formed over many millions of years ago by the hydrothermal decomposition of granite rocks, Kaolin (kaolinite) is essentially a hydrated aluminium silicate crystalline mineral. Kaolinite – widely known as Kaolin clay or china clay- is one of the most common minerals found on earth with the chemical make-up of Al2Si205(OH)4.

Kaolin or Kaolin clay might be an inconspicuous mineral yet extremely essential for the countless industries. It is significantly used to improve performance, cost reduction, efficiency increment and enhancing the value of processes and end products like paints, ink, ceramics, cosmetics, plastics, rubber and adhesives amongst others. In addition, it is extensively used in Pharmaceutical industry for liquid medicine and medical powders.

Paints:

Fine Kaolin can be used to reduce the quantity of Titanium Dioxide (TiO2) and in turn to decrease formulation cost and to improve rheology. Coarse Kaolin however do not offer much scope extending TiO2 but it does enhance the dry film property of primers and undercoats. Moreover, it is widely used in paints due to their ability to give opacity and viscosity.

Rubber:

Rubber benefits from Kaolin clay powder as it provides semi-reinforcing property to it. From tyres, belts, plugs, gaskets, mats to other innumerable extruded & fabricated parts, Kaolin tremendously helps to meet the demands of the broad customer base.

Adhesives:

In sealants and adhesives, Kaolinite clay is used as extender to alter their rheological properties due to its lower cost and superior reinforcing properties.

Cement:

Kaolin is a highly desired specialty mineral for cement and brick industry. It protects swimming pool systems and colour brick finishing from environment and other harsh conditions.

In many other cases, Kaolinite is engineered utilizing natural aluminosilicates and then refined using meticulous processes to further enhance its performance.
