Calcite powder
White Calcite Powder is widely used in plastics as filler
Calcium Carbonate is very common and widespread mineral with highly variable forms and colors.The use of calcite is dictated by its level of purity. Calcite is generally used as a filler material in a wide range of end-use industries, such as paper and pulp, paints and coatings, polymers and plastics and adhesives and sealants.

Why Calcium Carbonate / Calcite from Udaipur
Plastics:
Due to higher levels of brightness and better lusture the calcite extracted here in Udaipur is best suited for plastic industries and products as master batch/PVCPipes/etc.
Paper:
It is a growing industry for Calcium Carbonate. These days soapstone and Calcite are used simultaneously in paper industry. Lesser abrasion index makes it best suitable for paper industry. Silica content in this material is <3% which causes lesser harm to machinery.
Pharmaceuticals:
After proper treatments this material can be used for pharmaceuticals and food grade industry. Also huge intake in FMCG goods (edible) is there for this product.
Cattle feed & Pesticides:
This product has a huge demand in these industries. As it is a good carrying agent.
