Calcium Carbonate Filler Masterbatch is a high-performance Plastic Masterbatch produced by compounding ultra-fine calcium carbonate (CaCO₃), polymer carrier resin (PE or PP), and specially formulated processing additives. It is widely used in the plastics industry to optimize production costs, improve mechanical properties, enhance processing performance, and increase manufacturing efficiency.
Today, Calcium Carbonate Filler Masterbatch has become one of the most important functional masterbatches for manufacturers of plastic packaging, injection molded products, films, pipes, raffia, and extrusion applications.
Composition of Calcium Carbonate Filler Masterbatch
A typical formulation consists of:
| Component | Typical Content |
|---|---|
| Ultra-fine Calcium Carbonate (CaCO₃) | 70–85% |
| PE or PP Carrier Resin | 15–25% |
| Processing Additives | 1–5% |
The exact formulation can be customized depending on processing technology, product requirements, and customer specifications.
Manufacturing Process
High-quality Calcium Carbonate Filler Masterbatch is produced through a carefully controlled compounding process to ensure excellent dispersion, consistent quality, and stable processing performance.
1. Raw Material Selection
Production begins with carefully selected raw materials, including:
- High-purity ultra-fine Calcium Carbonate (CaCO₃)
- Virgin PE or PP carrier resin
- Functional processing additives
- Dispersion and compatibility agents
Every raw material is inspected before production to ensure compliance with quality specifications.
2. Material Preparation
Before compounding:
- Calcium Carbonate is dried to minimize moisture.
- Polymer resin is prepared according to the required application.
- Additives are accurately weighed and blended.
Precise formulation is essential for maintaining consistent product quality.
3. Twin-Screw Compounding
The blended materials are processed using advanced twin-screw extrusion technology.
During this stage:
- Raw materials are uniformly mixed.
- Calcium Carbonate is evenly dispersed throughout the polymer matrix.
- Melt temperature and screw configuration are carefully controlled.
This process produces a homogeneous compound with excellent processing characteristics.
4. Pelletizing and Cooling
The molten compound is extruded into strands, cooled, and pelletized automatically.
The finished pellets provide:
- Uniform particle size
- Excellent dispersion
- Smooth surface finish
- Stable processing performance
5. Quality Inspection
Each production batch undergoes comprehensive quality control before shipment.
Typical quality inspections include:
- Calcium Carbonate content
- Moisture content
- Melt Flow Index (MFI)
- Pellet uniformity
- Dispersion quality
- Mechanical performance
- Whiteness and color consistency
Only products meeting internal quality standards are approved for delivery.
Advantages
Calcium Carbonate Filler Masterbatch provides numerous technical and economic advantages.
