Understanding Masterbatch

Masterbatches are composed of mixtures containing specific additives and pigments. Plastic manufacturers use masterbatches to improve the properties of raw polymers or to color them as desired.

The process of making a masterbatch is straightforward. To produce a masterbatch, the manufacturer selects particular ingredients and heats them together at high temperatures in a carrier resin, allowing the mixture to cool. Once cooled, the masterbatch is cut into pellets and packaged for distribution.

When the plastic manufacturer receives the masterbatch, it is added to the raw polymer as part of the process to create a final, market-ready product.

  • White Masterbatch: Essential for industries that use for blowing film and casting film, injection and extrusion etc. Basic carriers are PE, PP, PET, ABS, EVA, etc.

  • Black Masterbatch: Used by manufacturers who produce black-colored products with diverse specifications, requiring black masterbatches with specific functionalities. Application for black masterbatch are used a lot for blowing films, such as garbage bag, HDPE pipes, etc.

  • Color Masterbatch: Used by manufacturers to achieve specific color schemes. Xinwancai’s labs create masterbatches that are not only color-accurate but also meet specific product functionality requirements. The application for color masterbatches are for films and extrusion, etc. 

  • PET Masterbatch: Used for PET sheets, PET bottles and containers, PET films, PET filaments, PET fiber yarns, etc.

  • PA Masterbatch: Used to improve the properties and coloration of polyamide (nylon) materials, and application for PA masterbatches are PA filaments, PA fiber yarns, PA66 30%gf for injection, PA films, etc.

  • Functional Masterbatches: Custom-designed to provide specific functionalities such as flame retardancy, anti-static properties, or improved mechanical strength. 

  • Flame Retardant Masterbatch: Use for PE films, PP, ABS, PET injections and extrusions, etc.

  • Processing Aid (PPA) Masterbatch: Improves the processability of various plastic products, including pipes, tubes, and cables.

  • UV Light Stabilization Masterbatch: Protects polymers from the damaging effects of UV light.

  • Antimicrobial Masterbatch: Designed for applications with strict antimicrobial, food contact, and biocidal regulations.

  • Slip Masterbatch: Reduces friction in plastic products, making them easier to handle and process.

  • Anti-fog Masterbatch: Prevents the formation of fog on plastic surfaces, ideal for food packaging and agricultural applications.

  • Optical Brightener Masterbatch: Enhances the appearance of plastics by making them brighter and more vibrant.

  • Modified Plastics/Engineering Plastics: PC/ABS, PP, PA, PBT(flame retardant, glass fiber, alloy, etc.)

Benefits of Advanced Masterbatches

Additive masterbatches offer numerous benefits, as any masterbatch producer will attest. Here are some key advantages:

  • Enhanced processability: Easier-to-process plastic is more cost-effective to manufacture and can improve in quality and functionality.
  • Improved protection: Certain masterbatches shield polymers from external conditions like UV light, climate, humidity, and chemicals, making products more durable and extending their lifespan.
  • Flame retardancy: A flame retardant masterbatch helps create thermally stable plastic products that are resistant to burning, meeting global safety regulations.
  • Anti-static properties: Anti-static masterbatches prevent static charges in plastics, which is vital for packaging electronics.
  • Precise appearance: Advanced color masterbatches ensure consistent color and are cost-effective during production.
  • Cost-efficiency: Using masterbatches in production is generally more cost-effective than alternatives, providing flexibility in the production process.
