Masterbatch for Colouring Plastics – Praharit Pigments


'Colouring plastic materials and polymer products' is the main application of masterbatches. It consumes 95% of the masterbatches produced globally. Being the most effective method is the reason behind its choice to color plastics. From the filaments to significant components are being colored using masterbatches. The desired color's target goal must be achieved at the end of the process, and for that precise and accurate method is to be developed. The desired color in plastic products always affects branding or aesthetic appearance. Numerous factors like the use of pigment, quality of pigments, the ratio of pigments with additives, the process of addition, and thermal considerations affect.

The most common application of masterbatch is the coloring of plastic materials. Masterbatch is the most effective method for coloring plastics. When producing filament to match the color of an existing end product, there can be a large number of components that affect the final color. Today, we shall discuss how the desired color may be achieved, whether it is for branding or aesthetic appearance.

The quality of specific colour in masterbatch depends upon:

  • Quality of pigments
  • The ratio of pigments with each other and with additives
  • Type of polymer to be colored (HDPE / PP / PVC / Nylon)
  • Colour of base polymer lot
  • Extrusion machine and process
  • Dispersing agent and uniformity of dispersion
  • Thermal consideration: Heat stability and temperature used in the process
Optimum levels of all of the factors mentioned above should be achieved and maintained to achieve accuracy and precision and accuracy in color production during masterbatch formulation. Accuracy & precision in the quality of pigments used in masterbatch helps in color produced in the end product.
