Application:

• As an anti-caking and free flow agents in chemicals, Insectcides/ Pesticides and     similar powdered materials due to its excellent water/oil absorption.
•  As a reinforcing agent in rubber.
•  As a functional extender in emulsion paints ensures film smoothness and acts as a
    buffer against acidity of the paint system.
• As a carrying agents in animal feedstuff, insecticides/pesticides,chemicals         due  to its very high water absorption, fine particle size and low bulk density.
•  To control rheological properties in a variety of applications.
