Activated Calcium Carbonate
To meet the market need, we have developed activated calcium carbonate based on local rich raw calcium carbonate . The product is mainly used as filler in areas of coating, paint, rubber, resin, etc, it would increase products’ property, and lower their cost.
The applications are as below:
1. Improve plastics stability, enhance the hardness and stiffness, and improve their heat resistance and astigmatic character.
2. It has high whiteness ,good liquidity and nice glossiness.
3. It has character of improving surface gloss and nice reinforcement for its low oil absorption and lubricant character.
4. Increasing products’ character for its lowering abrasion to processing machinery.
5. When applied in paint, it would lower paint’s cost for the high filling character to solid, and it has lower resistance to corrosion, and lower viscosity.
