What it does
Calcium carbonate masterbatch — high-loading filler concentrate on a PE carrier resin. Reduces resin consumption per kilogram of finished film or moulding without compromising mechanical performance at standard let-down ratios.
Typical applications
- Blown film (HDPE / LDPE shopping bags, liner film)
- Injection moulding (housewares, crates)
- Profile extrusion (pipe, sheet)
- Raffia and woven sacks
