Product Overview
Shunchang Calcium Carbonate Filler Masterbatch is an advanced polymer additive combining high-purity, finely ground CaCO₃ particles uniformly dispersed in PE or PP carrier resins. Designed for global plastic converters, it replaces a portion of high-cost virgin polymer resin without compromising structural integrity or output stability.
Key Performance Highlights:
- High CaCO₃ Loading: 70% to 85% concentration levels.
- Superior Dispersion: Advanced twin-screw extrusion prevents particle agglomeration and eliminates surface defects.
- Dust-Free Operation: Clean and safe handling compared to raw mineral powder.
- Process Stability: Consistent melt flow index and batch uniformity.

FAQ
Q: Will this masterbatch require changes to my machine settings?
A: No. Due to optimized pellet uniformity and melt flow index, it integrates smoothly into existing PE and PP processing lines with minimal adjustment.
Q: Do you provide trial samples?
A: Yes. Sample testing is fully supported, accompanied by complete technical documentation prior to bulk ordering.
Q: Can formulations be customized?
A: Yes. We offer custom carrier resins, specific additives, and tailored CaCO₃ loading levels to meet exact mechanical requirements.
