Description
Uncoated Calcium Carbonate Powder is a fine, white, odorless powder made from naturally occurring limestone. It is ground into a fine powder without any surface treatment or coatings, making it hydrophilic and prone to absorbing moisture.
Raw material is exploited from MONG SON mountain Pit with highest purity limestone that is one of top 5 sources in the world comparing with Brazil, Malaysia, Egypt.
