The importance of masterbatch in the world and its future

According to Market Research Future, the global masterbatch market is expected to reach $15.81 billion by 2028, with a growth rate of 6.6%. These figures show that masterbatch is one of the key factors in the growth of the global plastic industry. With the benefits it brings, Masterbatch will be widely used in the future. Earlier, we got acquainted with the masterbatch production process. Now we will discuss the classification and applications of masterbatch in the polymer industry.

What does masterbatch mean?

According to the information provided in the search results, a masterbatch refers to a concentrated mixture or compound containing:

  1. A polymer carrier resin or matrix (e.g. polyethylene, polypropylene) that is compatible with the main plastic to be used.
  2. Pigments, colorants and/or additives (e.g. UV stabilizers, flame retardants, antioxidants) at high concentrations.
  3. Sometimes a compatibilizer agent to aid dispersion of the additives in the polymer carrier.

The masterbatch is produced by melting and mixing the polymer carrier with the pigments/additives using heat and high shear. It is then cooled and cut into pellets or granules.The key purpose of a masterbatch is to allow efficient incorporation and uniform dispersion of colorants or functional additives into the main plastic material during manufacturing processes like injection molding or extrusion. The masterbatch pellets are added and diluted into the main plastic resin at a controlled ratio to impart the desired color or properties to the final plastic product.In summary, a masterbatch is a concentrated, pre-dispersed and easy-to-handle solid mixture used to color plastics (color masterbatch) or impart specific functional properties (additive masterbatch) to the main plastic material during processing

What is the application of masterbatch in the polymer industry?

Masterbatch is a very practical and vital tool that is used in various industries. The role of using masterbatch in the polymer industry is very important and fundamental in the field of coloring all kinds of plastic products and increasing its functional properties. Based on these applications, masterbatches are divided into 3 main categories: colored masterbatches (black, white and colored), additive masterbatches (clarifying, smoothing, stabilizing, anti-wear, etc.) and filling masterbatches (calcium carbonate , talc, mica and …). Masterbatch’s extraordinary advantages make it an essential component in many plastic processing methods. Therefore, according to the mentioned categories, the use of masterbatch in the polymer industry is also divided into different branches.

1- Application of color masterbatch

How do most plastic products get their custom colors? The answer is to use color masterbatches. Color masterbatches contain very specific pigment mixtures that are blended according to exact color requirements. After these pigment mixtures are created, they are injected into base polymers. This injection process, which takes place during the manufacturing stage of the product, is what gives the product its particular color or color. Color masterbatch is currently used in various industries and businesses such as textile, automotive, packaging, construction, electronics, etc.
