Unlike using raw calcium carbonate powder directly, a masterbatch formulation ensures better compatibility, consistent dispersion, and minimal dust generation, making it safer and more convenient to handle.
Key Features of Calcium Carbonate Filler Masterbatch
-
High Dispersion Quality
The calcium carbonate is finely milled and uniformly dispersed in the carrier resin, preventing particle agglomeration and ensuring smooth processing. -
Enhanced Mechanical Properties
Adding calcium carbonate improves rigidity, tensile strength, flexural modulus, and dimensional stability. This makes products more durable and resistant to deformation. -
Thermal Stability
Calcium carbonate filler improves heat resistance, reducing shrinkage and warping during processing or under high-temperature usage conditions. -
Cost Efficiency
As a cost-effective filler, calcium carbonate reduces the overall consumption of expensive base polymers without compromising product quality. -
Surface Finish Improvement
It enhances the surface smoothness of plastics, which is beneficial for printing, painting, or coating applications. -
Wide Compatibility
Suitable for various thermoplastics such as Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), ABS, and other engineering plastics.
