PLA & PETG Color Masterbatch for 3D Printing Filament, Injection Moulding and Extrusion

COLOR MASTERBATCH FOR BIOPLASTICS AND ENGINEERING APPLICATIONS

PLA & PETG Color Masterbatch for 3D Printing Filament, Injection Moulding and Extrusion

EXTRUTEX supplies color masterbatch formulated for PLA and PETG plastic materials, providing consistent color solutions for 3D printing filament production, injection moulding, extrusion, calendering and casting applications.

Our PLA and PETG color masterbatch range is designed for plastic processors and 3D printing filament manufacturers looking for convenient color adjustment, uniform dispersion and reliable processing performance. Available color options include green, yellow, black and other customized colors according to customer requirements.

With a recommended addition ratio of approximately 6%, the masterbatch can be blended with compatible PLA or PETG plastic pellets before processing. This allows manufacturers to produce colored filament and other plastic products without purchasing fully pre-colored raw materials for every color requirement.

Product Specifications

The specifications above reflect the available product information. Detailed technical values, including pigment concentration, melt flow rate, moisture content, density, particle form and packaging, should be confirmed for the selected color and carrier grade.

Available Colors and Custom Color Solutions

EXTRUTEX offers different color options for PLA and PETG processing. Color masterbatch allows manufacturers to adjust the appearance of their finished products while maintaining a consistent production formulation.

For customized orders, customers can provide a physical color sample, RAL reference, Pantone reference or another agreed color standard. Color matching should be evaluated in the actual base resin and finished product because processing conditions and material transparency can affect the final appearance.

PLA Color Masterbatch for Biodegradable 3D Printing Filament

Polylactic Acid (PLA) is a widely used bioplastic in desktop 3D printing. It is valued for its relatively easy processing, good dimensional stability in many printing applications and availability in a broad range of colors and formulations.

PLA color masterbatch provides a practical way to introduce pigments into natural or uncolored PLA resin. By blending the masterbatch with PLA pellets, filament manufacturers can produce colored 1.75 mm, 2.85 mm or other filament diameters according to their extrusion line configuration.

Typical PLA Filament Applications

• Desktop FDM and FFF 3D printing filament.
• Colored PLA filament for consumer and professional printing.
• Prototype parts and product models.
• Decorative objects and display products.
• Educational and creative 3D printing materials.
• Customized filament colors for commercial brands.

Important PLA Material Considerations

PLA is commonly described as a biodegradable or compostable bioplastic, but actual biodegradation depends on the PLA grade, product design and disposal environment. Industrial compostability is not the same as rapid decomposition in soil, water or a home composting environment.

Adding color masterbatch does not automatically make the finished material certified compostable or biodegradable. The complete formulation, including pigments and carrier materials, must be assessed against the applicable certification requirements if environmental claims are intended.

PETG Color Masterbatch for Injection Moulding and Extrusion

PETG is a glycol-modified polyester commonly used in extrusion, sheet production, thermoforming and injection moulding. It offers a useful combination of transparency, toughness, impact resistance and processing versatility.

PETG color masterbatch can be used to introduce color into suitable PETG resin formulations. It is suitable for manufacturers producing colored components, transparent or translucent products where the pigment system permits, and a range of extruded plastic products.

Typical PETG Applications

• Injection-moulded plastic components.
• Extruded PETG sheets and profiles.
• Transparent, translucent or opaque colored products, depending on the pigment formulation.
• Display and packaging components.
• Consumer product housings and accessories.
• Specialized 3D printing filament production.

For transparent or translucent PETG products, the selected pigment and masterbatch formulation must be evaluated carefully. Some pigments provide opaque colors, while others may be suitable for transparent or translucent effects.

Suitable Plastic Processing Methods

1. 3D Printing Filament Extrusion

Mix PLA or PETG resin pellets with the corresponding color masterbatch before feeding the material into the filament extrusion line. The compound is melted, homogenized, extruded through a filament die, cooled and calibrated to the required diameter.

Consistent mixing and extrusion conditions help achieve uniform color throughout the filament. Filament diameter, ovality, surface appearance and mechanical properties should be monitored during production.

2. Injection Moulding

Color masterbatch can be blended with compatible PLA or PETG pellets before injection moulding. The mixture is plasticized in the injection unit and transferred into the mould to produce colored components.

Mixing quality, dosage accuracy, melt temperature and residence time influence the finished color and surface appearance.

3. Plastic Extrusion

For extrusion applications, masterbatch is mixed with the corresponding base resin before processing through the extruder. Depending on the product, this can include profiles, strips, rods and other extruded plastic components.

4. Calendering

Color masterbatch can be incorporated into compatible polymer formulations for calendered sheet and film production. The masterbatch should be evaluated for dispersion, processing stability and compatibility with the selected resin.

5. Casting

For suitable casting processes, color masterbatch can be introduced into the compatible polymer formulation before forming. The processing method and material system must be checked to ensure the masterbatch can disperse correctly and achieve the required final appearance.

Recommended Addition Ratio: 6%

The recommended masterbatch addition ratio for this product is approximately 6% of the total mixture, subject to confirmation through production trials.

The calculation uses 6% of the total finished mixture. If the addition ratio is instead defined as 6 parts of masterbatch per 100 parts of base resin, the final percentage will be slightly different. Confirm the manufacturer's dosage convention before large-scale production.

The optimum addition ratio may vary with color strength, pigment concentration, product thickness, base resin color, required opacity and processing conditions. Conduct a trial to confirm the final dosage and color performance.

How to Use PLA and PETG Color Masterbatch

1. Select the correct carrier: Use PLA-based masterbatch with compatible PLA resin, or PETG-based masterbatch with compatible PETG resin.
2. Check material condition: Keep the base resin and masterbatch clean and protected from moisture and contamination.
3. Measure the dosage: Weigh the base resin and color masterbatch accurately according to the selected formulation.
4. Mix the materials: Blend the masterbatch and plastic pellets until the mixture is sufficiently uniform.
5. Feed the processing equipment: Transfer the mixture into the filament extrusion line, injection moulding machine or other suitable equipment.
6. Check the finished product: Evaluate color uniformity, surface appearance, processing stability and mechanical properties.
7. Adjust if necessary: Fine-tune the dosage or processing parameters based on trial results and the required product specification.

For production involving several colors, use suitable cleaning procedures when changing colors to reduce cross-contamination from previous material.

Advantages of Using Color Masterbatch

Storage and Handling

• Keep the masterbatch in its original packaging until use.
• Store in a clean, dry and well-ventilated warehouse.
• Protect the material from moisture, dust and other contamination.
• Keep bags sealed after opening when the material is not in use.
• Follow the manufacturer's recommended storage temperature and shelf-life information.
• Use appropriate drying procedures when required by the base resin or masterbatch supplier.
• Consult the product's technical data sheet and safety data sheet before processing.

Moisture control is particularly important for polyester-based materials such as PETG and for PLA processing. Excessive moisture during melt processing can contribute to polymer degradation and reduced finished-product performance. Follow the drying instructions for the actual resin and masterbatch grades.
