Calcium Carbonate Powder is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler and stabilizing agent. It is used as a coating pigment due to its special white color. It helps to increase the brightness of the opaque thin to medium thickness papers or to give them an excellent texture. This powdered compound is available in aplastic package of various different sizes as per the client's requirements.‚
Occurs in three natural forms such as lime stone, chalk and Marble. The chemical formula of calcium carbonate is CaCO3. Naturally its forms between the reactions of calcium, salt and carbon dioxide. this process is still going on in the oceans. Calcium carbonate that have the high purity, degree of whiteness and homogeneity are acceptable is commercial extraction worthwhile.
After quarrying further treatment is required to process natural calcium carbonate of high quality ,known generically as Ground calcium carbonate( GCC). Ground calcium carbonate is manufactured by grinding lime stone or marble because of their high brightness and purity. These automated processes have been developed and continuously improved in-house for decades and this outstanding experience guarantees that particle size distribution and brightness are perfectly adapted to the application.
Calcium carbonate powder of epic is one of the additives and popular materials Used in a variety of Application such as a - filler masterbatch, paints, paper, rigid pvc pipe, plastics, Rubber pigments, ceramics & glass and construction, etc.
