Filler Optimization Solution with Calcium Carbonate for Plastic Application

A plastic products manufacturer contacted us seeking calcium carbonate (CaCO₃) as a filler to reduce production costs. However, they had previously faced issues such as poor dispersion and reduced mechanical strength when increasing filler loading.

Our technical team evaluated the customer’s production process and product requirements. Instead of recommending a standard grade, we suggested a surface-treated calcium carbonate with controlled particle size and better compatibility with polymer matrices.

We provided:

· Optimized particle size distribution

· Surface treatment to improve dispersion

· Technical guidance on filler loading ratio

After implementing our recommendation, the customer achieved:

· Improved dispersion in the polymer matrix

· Maintained mechanical strength at higher filler levels

· Reduced overall production cost

This project highlighted our ability to deliver cost-effective and performance-balanced solutions, resulting in repeat orders and long-term cooperation.
