Filler Masterbatch & CaCO₃ Compounds
Ultra-fine, stearic-coated calcium carbonate compounds reduce raw material cost, shorten cooling cycles thanks to better thermal conductivity, and add stiffness, all while keeping film tensile properties and surface quality intact.

FAQ
Questions about calcium & filler compounds
What is filler masterbatch?
Filler masterbatch, also called a filler compound, carries a high loading of mineral filler, usually calcium carbonate (CaCO₃), in a polymer carrier. Converters add it to polyolefins to lower raw material cost and add stiffness. CP-CA80-PE holds 80% stearic-acid-coated CaCO₃ in a virgin LLDPE-based carrier.
How much calcium carbonate filler can I add?
From the CP-CA80-PE TDS: 15% – 45% in HDPE shopping and garbage bags, 8% – 25% in LLDPE/LDPE packaging film, 10% – 35% in injection-moulded housewares and 3% – 12% in PP woven sacks and raffia tapes.
Will filler weaken my film or tapes?
Particle size and coating decide it. A 1.5 μm average, a top cut of 6 μm or less and a stearic acid coating keep thin films smooth and help prevent tape splitting, with ≤ 0.01% retained on a 45 μm mesh. Confirm your loading in a line trial.
Why do filled films and parts cool faster?
Calcium carbonate conducts heat better than polyethylene, so filled melts set sooner and mould cycles shorten. Above 25% loading on blown film, raise the feed zone 5°C – 10°C and lower the die temperature slightly.
