One of the most common questions from plastic manufacturers is:
“How much calcium carbonate can be added to a plastic formulation?”
The answer depends on the application, product requirements, and processing conditions.
For injection molding products, calcium carbonate loading levels typically range from 10% to 30%.
For filler masterbatch production, loading levels can reach 70% to 85% depending on the carrier resin and application.
For blow molding and film applications, lower loading levels are often recommended to maintain product toughness and processing stability.
✅ Typical Loading Levels:
• Injection Molding: 10%-30%
• Blow Molding: 5%-20%
• Filler Masterbatch: 70%-85%
• PVC Products: 10%-50%
The right calcium carbonate grade can help manufacturers achieve cost reduction without compromising product quality.
Choosing the proper particle size, surface treatment, and oil absorption value is just as important as determining the loading percentage.
