Main Use
Calcium carbonate in masterbatch is used in plastics and is compatible with most polymers. It improves part stiffness and hardness.
What it does
- Improves resin hardness
- Provides greater stiffness
- Helps reduce production costs by replacing part of the polymer
Applications
| Process | Main Benefits |
|---|---|
| Injection | Improves dimensional stability; reduces costs |
| Extrusion | Improves material flow; reduces shrinkage |
| Blow molding | Increases crack resistance; improves stiffness |
Plastic resins where it can be used
It can be used with a wide range of plastic resins such as:
- High-Density Polyethylene
- Low-Density Polyethylene
- Linear Low-Density Polyethylene
- Polypropylene
- Polystyrene
- High- or Medium-Impact Polystyrene
- Non-translucent PVC compounds
- SAN
- TPU
- EVA
Recommended Dosage
- Dosage: between 15 and 20 grams in extrusion, and 10 to 100 grams in injection and blow molding, depending on the application.
- Ensure good powder dispersion to avoid clumps.
- Check that the particle size is suitable for the resin you use.
