Calcite powder, a natural form of calcium carbonate, is widely used as a filler in plastics, including polyvinyl chloride (PVC), to enhance material performance.

• Stiffness: Calcite powder increases the stiffness of the polymer matrix.
• Impact resistance: Smaller particle sizes help improve impact resistance.
• Viscosity: Since calcite powder does not melt during processing, it increases the viscosity of the PVC compound.
• Surface finish: Provides a smooth and uniform surface finish.

Calcite powder also offers additional benefits such as high dispersibility, low oil absorption, easy processing, excellent compatibility with polymers and organic additives, and outstanding dimensional stability, making it highly effective for plastic applications.
