Both calcium carbonate and talc powder are widely used in PP modification, but they offer different performance advantages depending on your application needs.

✔ Calcium Carbonate:
• Lower raw material cost
• Good for high-filling applications
• Improves stiffness and processing efficiency
• Commonly used in sheets, injection molding, and packaging

✔ Talc Powder:
• Higher rigidity and heat resistance
• Better dimensional stability
• Lower shrinkage and warpage
• Ideal for automotive parts and appliance plastics

So how do you choose?
If your priority is cost reduction, calcium carbonate is often preferred.
If you need better rigidity, heat resistance, and structural performance, talc powder is usually the better solution.

The right formulation depends on your product requirements and processing conditions.
