Kaolin China Clay
A high-purity hydrated aluminium silicate with excellent whiteness, fine particle size, and chemical inertness for paper, paints, ceramics, and polymers.
Product Overview: Kaolin (China Clay)
Kaolin (China Clay) is a naturally occurring hydrated aluminium silicate mineral known for its fine particle size, high brightness, chemical inertness, and non-abrasive texture. It is a critical functional filler and extender used across paper, ceramic, paint, rubber, plastic, and cosmetic industries.
Sakthima supplies refined and levigated kaolin clay processed under stringent quality controls, ensuring high whiteness, uniform particle distribution, and optimal rheological properties for diverse manufacturing applications.
