Samples: Customizable according to customer specifications.
Capacity (per year): 10,000 T/year.
Characteristic
Kaolin is a special type of clay formed through hydrothermal processes or natural weathering. Composed mainly of the mineral kaolinite, it can be blended with other components such as illite, montmorillonite, quartz, and various other minerals to enhance its natural friability, exceptional heat resistance, pure white color, and ultra-lightweight properties.
One of Kaolin’s most distinctive characteristics is its ability to disperse in water. When mixed with water, it becomes thick and malleable, making it highly adaptable for various applications. Thanks to these outstanding properties, Kaolin is widely used across numerous industries and everyday life.
