Exploring the Properties and Applications of Kaolin
Kaolin is a clay mineral often used as a filler or reinforcing agent in polymeric materials. It is a white, soft powder that is derived from the mineral kaolinite. When added to polymers, kaolin can improve their mechanical properties, such as strength, stiffness, and impact resistance. This is due to its unique plate-like structure, which acts ...
