Masterbatch: A General Definition

Masterbatches are made from blends that include specific additives and pigments. Plastic manufacturers use masterbatches to enhance the qualities of certain raw polymers, or to color them in the color of their choice.

The masterbatch production process is relatively easy to describe. To create a masterbatch, the masterbatch manufacturer selects specific ingredients and heats them together at a very high temperature in a carrier resin – and then allows the outcome to cool off. Once the masterbatch has cooled, the masterbatch manufacturer cuts it into pellets and packages them for delivery.

After the plastic manufacturer receives the masterbatch, it adds it to the raw polymer, as part of the process that eventually creates a finished, marketable product.

The composition of a masterbatch mainly includes pigments, additives, and a polymer base. Pigments can be organic or inorganic and determine the colour and some properties of the final material. Additives, on the other hand, provide additional characteristics such as UV resistance, anti-static properties, or flame retardancy. The polymer base acts as a carrier for the pigments and additives, facilitating their incorporation into the plastic material during the manufacturing process. This combination ensures uniform coloration and consistent properties in the final product, which is key in industries that depend on high precision in color and material properties.

Advantages of Using Masterbatch

Using masterbatch in plastic product manufacturing offers numerous advantages:

• Customized formulations for each application: In the plastics industry, each application has specific requirements. Masterbatches can be custom-formulated to meet these needs, ensuring that the final products have the exact properties required.
