Global Leader in Calcium Carbonate Masterbatch for Plastics

Calcium Carbonate Masterbatch: What It Is and Why It Matters

Calcium carbonate (CaCO₃) masterbatch is a highly concentrated blend of CaCO₃ or talc that is pre‑mixed into a thermoplastic resin. The result is a dust‑free, uniformly dispersed filler that improves flow, reduces processing time, and cuts material costs without compromising product quality.

Key benefits include:

• Consistent particle size for predictable melt behavior
• Reduced viscosity and easier extrusion or injection molding
• Improved mechanical properties such as stiffness and impact resistance
• Lower overall material cost by replacing a portion of the base polymer

Applications by Polymer Type

• Polypropylene (PP) Masterbatch – Ideal for packaging, bags, building materials, and automotive interiors.
• Polyethylene (PE) Masterbatch – Used in non‑woven fabrics, films, and flexible packaging.
