Carbon black masterbatch possesses outstanding colouring power and dispersibility, making it a commonly used colourant in plastic product manufacturing. However, many purchasers often prioritise price over the distinct characteristics of different masterbatch types during selection.
Variations in dispersibility, weather resistance, processing adaptability, and long-term stability exist across different carbon black master batch types. When procuring black masterbatches, it is essential to systematically understand the types of black masterbatches and their corresponding application scenarios, taking care to avoid selection pitfalls, minimise trial-and-error costs, and optimise procurement efficiency.
Types of Carbon Black Masterbatch
Carbon black masterbatches can typically be categorised across three dimensions: blackness difference, functional properties, and resin carrier. Below, we explore the types of black colour masterbatches.
Blackness Grades and Applications of Carbon Black Masterbatch
| Basic black colouring | Blackness | Dispersion Requirement | Cost | Typical Applications |
|---|---|---|---|---|
| High Blackness Carbon Black Masterbatch | High blackness, deep appearance | High | Relatively high | Automotive exterior parts, high-end injection molded products |
| Medium Blackness Carbon Black Color Masterbatch | Balanced blackness and performance | Medium | Medium | Home appliance housings, general injection molded products |
| Standard Blackness Carbon Black Colour Masterbatch | Basic black coloring | Low | Low | Industrial structural parts, daily-use products |
- High-blackness masterbatches are used in products requiring premium aesthetics and deep colour intensity. They deliver pure black expression but demand sophisticated dispersion systems and production processes, resulting in higher overall costs.
- Medium-blackness masterbatches offer a favourable balance between blackness, processing adaptability, and cost, making them the choice for most plastics manufacturers.
- Standard carbon black master batches satisfy basic colouring needs, suitable for plastic products where appearance quality is less critical but cost control is paramount.
Once the blackness grade is determined, functional properties must also be considered during selection.
Functional Performance Classification of Carbon Black Masterbatches
| Type | Main Function | Performance Characteristics | Typical Applications |
|---|---|---|---|
| Standard Coloring | Coloring | Stable blackness | Packaging, daily-use products |
| UV Resistant / Weatherable | Anti-aging | UV absorption | Pipes, outdoor products |
| Conductive / Antistatic | Electrical resistance control | High dispersion requirement | Cables, electronic packaging |
- Standard black masterbatches fulfil basic colouring requirements, suitable for indoor products or items without functional specifications.
- UV-resistant/weatherproof masterbatches prioritise UV absorption, delaying ageing in outdoor plastic applications such as pipes and municipal infrastructure.
- Conductive/antistatic masterbatches are employed in products or scenarios demanding surface resistance control, requiring stringent carbon black and dispersion management.
After understanding the blackness and functionality of masterbatches, note that the resin carrier used in carbon black colour masterbatches must exhibit good compatibility with the final product.
Carbon Black Masterbatch Resin Carrier Selection
| Resin Carrier | Processing Characteristics | Suitable Processes | Typical Applications |
|---|---|---|---|
| PE Carbon Black Masterbatch | Good flowability | Extrusion, blown film | Films, pipes |
| PP Carbon Black Master batch | Stable molding | Injection molding, extrusion | Home appliance housings |
| Engineering Plastic Carrier | High heat resistance | Injection moulding, extrusion | Automotive, electronics |
- PE black masterbatch suits extrusion and film blowing processes, widely used in film and pipe products.
- PP black masterbatch performs stably in injection moulding, commonly employed for appliance casings and similar items.
- Regarding engineering plastics like ABS, PET, and PS, processing demands high temperature control. Without a compatible carrier, issues such as poor dispersion or unstable performance often arise.
Carbon black colour master batch types must be highly matched to application scenarios; excessive blackness or functional properties incur unnecessary costs.

Next, we address common issues and misconceptions in procurement selection to reduce trial-and-error risks.
Common Issues in Carbon Black Masterbatch Selection
During actual procurement, the following factors frequently impact masterbatch selection:
Operating Environment: Is the product intended for outdoor use or prolonged exposure to high-ageing conditions?
Aesthetic Requirements: Are there explicit standards for blackness and colour consistency in the finished product?
Resin and Process: Are the resin type and processing method compatible with the selected carbon black master batch?
Procurement Cycle: Is this a short-term order or does it require a long-term, stable supply?
Common Procurement Pitfalls:
- Focusing solely on price while overlooking differences in masterbatch types
- Substituting functional products with standard black masterbatches results in substandard performance
- Relying solely on initial sample performance while disregarding long-term batch consistency
Acknowledging these issues ensures stability in mass production and product quality. Furthermore, purchasers should select masterbatch suppliers with professional support capabilities.
