China Clay - Hydrated Aluminium Silicate, Lump/noodles/powder Form, White/off-white Appearance, 10% Max Moisture Content, Excellent Plasticity And Viscosity Properties, Ideal For Paints, Papers, Ceramics, Cosmetics, And Electrical Insulation

By
incorporating rich industry experience, we are involved in offering
China Clay. This is a natural mineral found in partly
decomposed granite, which is an igneous feldsparic rock. Most
abundantly available clay in the Earth's crust, this is a earthy,
soft, usually white to off white and sometimes reddish in color. This
China Clay is carefully produced by our professionals by the
chemical weathering of aluminum silicate minerals like feldspar. This
clay is widely used in following industries:

• Paint
  industry
• Paper
  industry
• Electrical
  industry
• Cosmetic
  industry
