Why Calcium Carbonate Powder is essential for Plastic Industry

Beyond cost, CaCO₃ improves the quality of plastic products. It enhances surface smoothness, increases gloss and opacity, and improves strength and stiffness when used correctly.

CaCO₃, maliyetin ötesinde plastik ürünlerin kalitesini artırır. Doğru kullanıldığında yüzey düzgünlüğünü artırır, parlaklığı ve opaklığı artırır, mukavemeti ve sertliği artırır.

Does Calcium Carbonate Really Reduce Costs?

Many believe that adding CaCO₃ lowers production costs, but it’s essential to look at both visible and hidden costs. As more CaCO₃ is added, the material’s density increases, reducing volume. This means cost savings should be calculated based on volume rather than weight—something many manufacturers overlook.

Why Add Calcium Carbonate?

Here are some key benefits of using CaCO₃ in plastic manufacturing:
✔ Provides a smoother surface (especially with finer particles)
✔ Reduces shrinkage and improves dimensional stability
✔ Remains thermally stable during processing
✔ Enhances impact resistance at the right levels (8 phr)
✔ Improves flowability and processability (8 phr)
✔ Increases hardness and compressive strength

CaCO₃ in the Edgebanding Industry

One challenge in edgebanding—especially with thinner materials—is the “telegraphing effect,” where surface imperfections from the underlying board become visible. Using CaCO₃ at optimal levels helps minimize these traces, resulting in a smoother finish.

While factors like chipboard quality and processing conditions also play a role, the key takeaway is that CaCO₃ is not just about cost savings. It enhances the performance and overall quality of edgebanding, leading to a better final product.
