Uncoated Calcium Carbonate Powder: Enhance Your Product Line

Uncoated calcium carbonate powder offers a range of benefits that can significantly improve product durability and performance across multiple industries. 

Our premium uncoated calcium carbonate is designed to provide superior adhesion, whiteness, and mechanical strength and ensure sustainability in your production processes.

What is Uncoated Calcium Carbonate Powder 

Uncoated calcium carbonate powder is a form of calcium carbonate (CaCO3) with no surface treatment or coating applied to the particles. This type of calcium carbonate is a naturally occurring mineral derived primarily from the sedimentation of the remains of marine organisms, such as shells and coral, over millions of years. Due to its chemical properties and cost-effectiveness, it is one of the most widely used minerals in various industries.
