2024-01-25

Heavy calcium carbonate powder (heavy calcium powder) for plastic masterbatch and color masterbatch: 400 mesh. It is required that the whiteness remains unchanged after high temperature heating. The ore structure is large crystalline calcite. Calcium carbonate content: 99%. Whiteness: 94%.
Calcium carbonate can play a skeleton role in plastic products, which plays a great role in the dimensional stability of plastic products. It can also increase the hardness of the products, improve the surface gloss and surface smoothness of the products, and improve the processing performance of the plastics. It has obvious effects on improving heat resistance, scratch resistance, smoothness and notch impact strength. Since the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments.
