What Is Masterbatch?
Masterbatch is a concentrated mixture of pigments, additives, or fillers encapsulated in a carrier resin. It is used in plastics manufacturing to impart color, properties, or performance enhancements to base polymers. Instead of adding pure pigments or additives directly to raw plastic, processors use masterbatch for better dispersion, consistency, and processing control.
Main Types of Masterbatch
Masterbatch is broadly classified into three major categories based on its function:
1. 着色母粒
Color masterbatch is used to give plastics consistent and vibrant colors. It contains a high concentration of pigments or dyes and is designed to mix evenly with base polymers.
- Standard colors: Red, blue, green, black, white, etc.
- Custom colors: Tailored to customer needs.
- Special effects: Metallic, pearlescent, fluorescent finishes.
2. Additive Masterbatch
These masterbatches impart functional properties to the plastic without affecting color.
- UV stabilizers: For outdoor durability
- Antioxidants: Prevent thermal degradation
- Antistatic agents: Reduce static buildup
- Slip and antiblock agents: Improve film processing
- Flame retardants: Enhance fire resistance
3. Filler Masterbatch
This type is used to reduce production costs and modify physical properties by incorporating fillers like calcium carbonate or talc.
- Cost-saving: Replaces expensive polymer content
- Improved stiffness: Especially useful in blown films and injection molding
- Enhanced printability and smoothness
Applications by Polymer Type
Masterbatches are formulated to work with specific base polymers. Charming Masterbatch provides targeted solutions for various resins:
1. PET (Polyethylene Terephthalate) Application
- Used in preforms, bottles, films, and fibers
- Color masterbatch ensures clarity and brightness
- Additives can provide UV resistance and barrier properties
2. PP (Polypropylene) Application
- Common in injection molding, non-woven fabrics, and packaging
- Color and additive masterbatch help maintain mold release, anti-fog, and thermal stability
3. PA6 (Nylon) Application
- Suitable for automotive, textile, and electrical components
- Requires high-temperature stable pigments and UV protection
4. PE (Polyethylene) Application
- Widely used in blow molding, film blowing, and pipes
- Masterbatches must offer good dispersion and processing stability

How to Choose the Right Masterbatch
Choosing the right masterbatch depends on several key factors:
- Polymer compatibility: Make sure the masterbatch matches your base resin (PET, PP, etc.)
- End-use application: Consider whether the product will need UV, thermal, or moisture resistance
- Processing method: Different processes like injection or extrusion may require different formulations
- Color matching needs: Choose a supplier like Charming that offers custom color development
- Environmental regulations: Ensure compliance with RoHS, REACH, FDA, etc., if applicable
