Calcium carbonate powder applications

1)RUBBER-Calcium carbonate is useful as an extender and in controlling the flow properties of products which are to be moulded or extruded. A widespread application is in latex carpet backing materials.10-30 micron of calcium carbonate powder is used to manufacture rubber.

2)PAPER-Fine grades of calcium carbonate are used extensively in paper manufacturing. Consistent particle sizing and colour are essential. As an alkali material it reduces acidity of paper, improving the durability of printed material.5-15 micron of fine grades of calcium carbonate powder is used to manufacture paper.

3)PAINTS-Calcium carbonate powder is used to bulk out or extend the resins & polymers in paints. Colour is obviously important and calcium carbonate is used as an aid to pigmentation, and also to help control the finish (matt or gloss).5-25 micron of calcium carbonate powder is used to manufacture paints.

4)ANIMAL FEED-

Animals need calcium carbonate for bone development, nerve function and to produce milk and eggs. Calcium carbonate contains the element calcium. ... Their high calcium and magnesium content make calcium carbonate and dolomite important components in animal feed. Calcium carbonate is used in both vitamins and premixes.125-150 micron calcium carbonate powder is used to manufacture animal feed.

5)ADHESIVES-

A wide variety of products including latex-based adhesives and sealing compounds , construction adhesives and wood putties rely on limestone as a filler. Consistent high-calcium chemistry is important to reduce the viscosity effects of magnesium and the wear and bonding strength deficiencies of silica.10-30 micron of calcium carbonate powder is used to manufacture adhesives.

6)FOOD ITEMS-

When used as food additives, calcium carbonate acts as an anti-caking agent an added source of calcium and a white food colour. It is also a nutrient for yeasts, an acid reducer and a firming agent. It also stabilise and thicken some products, and be used to strengthen dough. The foods in which it is used is Breakfast cereal, Nutritional bars, Baked foods, Fortified beverages, cookies , crackers , food and sauces. 28 micron of calcium carbonate powder is used in these food items.

7)FIBER GLASS-

The calcium carbonate increases the tensile strength , flexural strength and impact strength of fiber glass.75 micron of calcium carbonate powder is used to manufacture fiber glass.

8) PLASTICS-

Calcium carbonate powder is widely used as a filler in plastic products, comprising up to 25% of the volume, adding density, improving rheology and reducing cost. Calcium carbonate is often blended or "coated" with additives such as stearates to aid bonding within the plastic.5-30 micron of calcium carbonate powder is used in plastic products.

NOTE-The calcium carbonate mesh size mentioned above may differ for the companies in these industries across India.
