At this size, your calcium carbonate masterbatch is capable of being incorporated for any polymer blend for any applications. The final result will always a flawless surface, no matter how thin.

Reduce cost

Calcium carbonate is about ten times cheaper than plastic so more filler content equates to more competitive cost.
With the incorporation of calcium carbonate masterbatch, some calcium carbonate will distribute at the surface layer of the plastic article to add roughness on a microscopic level, the finer the particle, the more expensive the roughness feel.

Enhances rigidity

The addition of calcium carbonate gives a denser structure and contribute the the entire polymer system’s stiffness due to its natural hardness as a mineral. Furthermore, because it is so small, the CaCO3 itself also functions as a nucleating agent that increases the crystallinity of the polymer matrix and hence, improving the overall stiffness and scratch resistance property.

Reduces cycle time

Plastic by itself is an insulator so by adding a mineral filler like calcium carbonate, the entire melt suddenly got enhanced thermal conductivity that allow it to heat up faster and cool down quicker which as a result reduce cycle time. This effect is even magnified by our micron-size filler that fills in the gaps between polymer particles better.
