CALCIUM CARBONATE LIGHT

'STAR BRAND' is precipitated calcium carbonate synthesized by chemical reaction with calcium hydroxide after calcination
of the best quality limestone and carbon dioxide.
The product is high quality light calcium carbonate containing less impurity and of good whiteness, and can be used for general
chemical uses.

EC grade is fine powder of high purity developed for uses of raw materials of electronic products and fine ceramics.

ME-L grade is a products which is improved workability and handling property by regulating of bulk density.
It can be used for general chemical uses, and further, for dentifrice, food additive, and bulk fine chemicals for repacking, prcessing,
and manufacturing.
