including activity and non-activity.
 

The Heavy Calcium Carbonate is almost always used for a raw material of goods.

1.

PLASTIC
The Heavy Calcium Carbonate is used for producing the various plastic products made from petroleum.

Adding the Heavy Calcium Carbonate makes the plastic product hard to be deformed as it increases the degree of intensity and stability. It also makes it good appearance and good touch with non slip and frosting.
Besides, It becomes easy to process by increasing flow and dispersion. 
Using the Heavy Calcium Carbonate saves the cost to produce because it is more inexpensive than petroleum and the other raw materials.

Plastic products which contains the Heavy Calcium Carbonate are as the following;

• Pipe, Gutter, Tile, Electric wire, Vinyl sheet, Parts of Electric product, Parts of Automobile, Toy, Film, Garbage bag, Container, Tableware, Food Tray, Dish Tray, Toilet table, Bedpan, Chair, Glue and so on.

2.

RUBBER
The Heavy Calcium Carbonate is used much for producing rubber products because it makes easy to process rubber. It is also useful for saving the cost as the filler.

Rubber products which contains the Heavy Calcium Carbonate are as the following;

• Chemical shoes, Electric cable, Tire, Belt, Hose, Sponge, Rubber paste, Rubber glue.

3.

PAINT
To add the Heavy Calcium Carbonate when producing the paint, it is effectual to adjust its viscosity, improve work to paint by preventing drip, and stop being absorbed on the surface of wood.

4.

PAPER
The Heavy Calcium Carbonate is used in paper manufacture.
It does not only makes the paper more white, but also makes it change from acidic to neutral. 
So it becomes good for preserving for long time without rot like newspaper which is acidic.

Papers which contains the Heavy Calcium Carbonate are as the following;

• Art paper, Coating paper, Gravure paper, High quality paper, Medium quality paper, Rice paper, Poster, and Atlas.

5.

BUILDING MATERIAL
Limestone and the Heavy Calcium Carbonate have been used for building since ancient times. 
In the present day, they are also used for the various building materials, for example, Artificial marble, Floor board, Wall board, and so on.

6.

FOOD ADDITIVE, MEDICINE
The Heavy Calcium Carbonate is used for the food additive and calcium ingredient of medicine because the crystalline limestone mined around Tohjoh town is pure and very good quality.

As the food additive, it is added to Boiled fish paste, Sausage, Bread, Chewing gum, Juice, Tofu, Cracker and so on. It is added to the Health food for calcium reinforcement, too.

As the medicine, it is used for Antacid in the medicinal powder for stomach, Excipiment adhering the effective ingredients, Polisher in tooth-paste, and Calcium pill.

7.

AGRICULTURAL PURPOSE, FEED
In agricultural field, the Heavy Calcium Carbonate is used for Hydration agent or Carrier of agricultural chemicals. It is also used for Neutralization agent of soil.

In field of stockbreeding and fishery, it is used for Combination feed, Calcium supplying pill which make the shell of egg or cultured prawn harder, and Medicine for animal.

8.

THE OTHERS
The Heavy Calcium Carbonate of high purity is used for Crystal glass, Optical glass like lens of camera, and Ceramics for electronic parts.

At the school, it is contained to Powder of white line on the ground, Chalk, Colors, Crayon, Pastel and Plastic Eraser.

In this way, the Heavy Calcium Carbonate is essential for producing various products.
