1,Improve the stability of plastic product size
The addition of calcium carbonate, which plays a role in the plastic products, has a great effect on the stability of plastic products.
2, improve the hardness and rigidity of plastic products
In the plastics, especially in the soft polyvinyl chloride, the hardness increases with the amount of calcium carbonate, and the elongation decreases with the increase of hardness. Fine particles, large oil absorption value of calcium carbonate, the growth rate of hardness. On the contrary, the crude oil absorption value of small particles of calcium carbonate, plastic hardness growth rate is small. In soft PVC, the growth rate of calcium carbonate is the smallest, and the precipitated calcium carbonate (light) is the second.
3, improve the plastic processing performance
The rheological properties of plastics can be changed by the addition of calcium carbonate. Calcium carbonate powder, in addition to the number of large, it will help it and other components of the mixture, but also contribute to the formation of plastic processing.
The addition of calcium carbonate, especially after the surface treatment of calcium carbonate, not only can improve the hardness of the product, but also can improve the surface gloss and surface smoothness.
The addition of calcium carbonate, can reduce the shrinkage of plastic products, linear expansion coefficient, creep properties, forming conditions for processing.
4, improve the heat resistance of plastic products
In general plastic products add calcium carbonate, heat resistance are improved, such as: in polypropylene, add about 40% calcium carbonate, heat resistance increased by about 200C. The filling ratio is less than or equal to 20%, temperature resistance increased from 8 to 130C.
5, reduce the cost of plastic products
Ordinary light calcium carbonate, heavy calcium carbonate is far lower than the price of plastic prices, calcium carbonate will reduce the cost of plastic products.
