What Is a Master Batch Color Code?
A master batch color code is a standardized formula or identifier used to classify, reproduce, and manage colors in plastic production. Each code represents a specific combination of pigments, carrier resins, and additives that ensure consistent coloration during extrusion, molding, film blowing, or fiber spinning. The master batch color code enables manufacturers to maintain repeatability across batches, factories, and product lines.
How Master Batch Color Codes Are Structured
- Pigment identification
- Carrier resin compatibility (PE, PP, PET, PA, ABS, etc.)
- Concentration levels & dispersion properties
- Additive functions (UV, anti-static, antimicrobial, etc.)
- Heat resistance and processing temperature
Why a Master Batch Color Code Chart Matters
A reliable master batch color code chart ensures precise color matching, reduced waste, and improved product consistency. Manufacturers depend on these charts to:
1. Maintain Brand Identity
Brands require exact replication of signature colors in plastics and fibers. The master batch color code provides a repeatable formula.
2. Improve Production Efficiency
By referencing an established master batch color code, production teams reduce trial-and-error costs and accelerate time-to-market.
3. Ensure Color Stability
Quality suppliers create master batches with optimal pigment dispersion, ensuring brightness, fade resistance, and improved durability.
4. Achieve Cross-Material Consistency
A reliable color code ensures that plastic, film, fiber, and molded parts maintain identical coloration—even when produced via different processes.
2025 Master Batch Color Code Chart
Below is a simplified version of the 2025 master batch color code chart used across many manufacturing sectors. Actual codes vary by supplier, but the structure remains consistent worldwide.
| Color Category | Master Batch Color Code Example | Pigment Type | Common Applications |
|---|---|---|---|
| Bright Red | MB-R302 | Organic Pigment Red | Household goods, toys, PP injection molding |
| Sky Blue | MB-B215 | Phthalocyanine Blue | Blow molding, films, PET bottles |
| Deep Black | MB-BK700 | Carbon Black High-Jet | Industrial parts, automotive components |
| Pure White | MB-W110 | Titanium Dioxide | Food-grade plastics, medical packaging |
| Emerald Green | MB-G410 | Organic/Phthalo Green | Garden tools, fibers, non-woven production |
| Metallic Silver | MB-S900 | Aluminum Flake | Electronics casings, cosmetics packaging |
| Transparent Tint Blue | MB-T102 | Solvent Dye | PET/PC bottles, optical parts |
The chart illustrates how each master batch color code corresponds with pigment families and technical uses. Manufacturers often customize these codes depending on carrier resin, melt temperature, dispersion requirements, and environmental performance.
Factors Affecting Master Batch Color Code Accuracy
1. Resin Type & Compatibility
Different plastics require different dispersion methods. The same master batch color code may behave differently in PP vs. PET.
2. Processing Temperature
High-heat polymers risk pigment degradation unless the master batch color code includes heat-resistant pigments.
3. Additives
Functional additives (UV stabilizers, flame retardants, anti-static compounds) may influence color appearance and opacity.
4. Pigment Strength & Dispersion Quality
Advanced twin-screw processing—like the technology used by top companies—ensures stable master batch color code performance.
5. End-Use Environment
Sun exposure, chemical exposure, humidity, and abrasion can affect long-term color stability.

How to Choose the Right Master Batch Color Code
1. Define Application Requirements
Packaging, fiber spinning, film blowing, and injection molding all require specific master batch color code formulations.
2. Evaluate Heat Stability
Polymers like PA or PET require pigments that can withstand higher melt temperatures.
3. Choose Precise Pigment Families
Organic, inorganic, phthalocyanine, metallic, and fluorescent pigments behave differently in masterbatch processing.
4. Request a Standardized Color Code Chart
Reliable suppliers—such as Charming Masterbatch—provide detailed master batch color code charts with clear tolerances.
5. Consider Functional Additives
UV-protection, antimicrobial agents, flame retardants, and antistatic additives may be required depending on end use.
6. Test Before Mass Production
A small sample run ensures the selected master batch color code performs correctly before full-scale manufacturing.
Frequently Asked Questions
1. What is the purpose of a master batch color code?
It provides a standardized formula to ensure consistent color reproduction across production batches.
2. Can master batch color codes be customized?
Yes—reputable companies create custom master batch color code formulations tailored to customer needs.
3. Are functional additives compatible with color masterbatch?
Most are—antistatic, flame retardant, and UV stabilizer additives can be integrated into a single formulation when engineered correctly.
4. How long do master batch colors remain stable?
With proper pigment selection and UV protection, most colors remain stable for years, even in outdoor conditions.
5. Can a master batch color code be used with multiple resins?
It depends on the carrier base—suppliers typically design resin-specific formulations.
