Calcium carbonate is widely used in plastics. Compared with other non-metallic mineral powder materials, calcium carbonate has obvious advantages. Perhaps many friends are not clear about it. Next, I will introduce to you in detail.

1. The price is cheap

Among various non-mineral powder materials, calcium carbonate is relatively cheap.

2. Good color, easy to color

Calcium carbonate can be used for light-colored plastic products. The disadvantage is that the color of colored plastic products is not bright enough, which is acceptable in most cases.

3. Low hardness

Its Mohs hardness is 3, which is much lower than the hardness of the steel used in manufacturing and processing machinery and molds (such as nitride steel, high-speed steel). Therefore, the filling plastic has an impact on the equipment parts (screws, barrels, etc.) and molds that are in contact. The wear is lighter.

4. Good thermal and chemical stability

The thermal decomposition temperature of calcium carbonate is above 800°C, and no thermal decomposition occurs at all plastic processing temperatures. Calcium carbonate is a strong base and weak acid salt, and its chemical stability is good except in acidic media.

5. Easy to dry, without crystal water, the adsorbed water can be removed by heating.

6. Non-toxic, non-irritating, and tasteless.

The above are the characteristics of calcium carbonate that the editor briefly introduced to you. If you have any questions or want to know, please contact us.
