Kaolin Powder

CALCINED KAOLIN POWDER

Being a well-reckoned Manufacturer, Exporter & Supplier, we are making available qualitative and cost effective Calcined Kaolin Powder in the global market. The advanced and modern processing techniques ensure consistent quality, low specific gravity, good whiteness and freedom from impurities at pocket friendly costs. We make due consideration on its packaging so that moisture free content reaches the buyers.

Calcined Kaolin Powder is an anhydrous aluminum silicate produced by heating hydrous china clay after water washing to high temperatures in a rotary kiln. The calcination process gives an increase in the original hardness of kaolin and alters the morphology of the kaolin particles completely.

When calcination process is done at around 700 degree Celsius, the dehydrogenate of the kaolin is complete, forming a partially crystalline Meta kaolin. Fully Calcined Kaolin products with an amorphous structure are formed around 1000 degree celsius.

Fully Calcined Kaolin’s Powder can be surface modified with functionalized coupling agent Silane to give a particle coating capable of chemically bonding with the polymer. After surface treatment, the dispersion of filler is also improved. In view of the reduced surface activity, calcined kaolin’s give good reinforcement and permanent set properties, at the same time maintaining very good processing conditions.
