What is masterbatch

What is masterbatch

In the world of plastics and chemicals, certain words and terms may seem confusing to people who are not experts in this field. One of these terms that are used frequently is “masterbatch”. But what is the meaning and concept of masterbatch and why is it important in plastic production?

Masterbatch is a polymer additive that is produced in a concentrated form and in the form of granules. This material is used to color (color masterbatch) or improve the properties of plastics (additive masterbatch) in the production process.

A masterbatch polymer can be thought of as a pigment or concentrated additive for plastics. Imagine you want to make a red plastic cup. Instead of adding red dye directly to the entire plastic, a red masterbatch is used. A plastic masterbatch is like a concentrated dye that is added to the plastic in very small amounts to create the desired color.

What is masterbatch? In other words, a masterbatch is an easy and precise way to color plastics and give them special properties.

Due to its high concentration, a masterbatch mixes easily with the original plastic, making the production process more efficient. It is widely used in industries such as packaging, automotive, home appliances, and pipe and fitting manufacturing.

What are the main components of a masterbatch?

To understand what a is masterbatch, we need to know its components and compositions. A masterbatch consists of three main components that determine its performance and quality together.

  • Pigment
  • Base polymer (carrier)
  • Additives
  1. Pigment
  • In Color Masterbatch: Pigments are used to provide color to the plastic
  • In Additive Masterbatch: Chemical additives are included to enhance properties like UV resistance, flame retardancy, anti-static behavior, or flexibility.
  • White Masterbatch: Titanium dioxide (TiO₂) is commonly used to achieve whiteness and opacity
  • In Filler Masterbatch: Fillers like calcium carbonate are added to reduce costs or improve mechanical properties.
  • Black masterbatch: Black carbon is commonly used to achieve blackness
  1. Polymer Carrier (Base Resin)
  • The polymer carrier acts as the base material and is typically the same type of polymer as the final product (e.g., polyethylene PE, polypropylene PP, or polystyrene PS).
  • It ensures compatibility and even dispersion of the pigment or additive in the final plastic product.
  1. Additives (Processing Aids)
  • These are used to improve the manufacturing process and performance of the masterbatch.
  • Examples include dispersing agents (to ensure even distribution of pigments), lubricants (to enhance flow), or stabilizers (to prevent degradation during processing).

Types of masterbatch

Masterbatch pellets are one of the main materials used in various industries for coloring and improving the properties of base materials. These compounds contain colorants, fillers, reinforcements, and other chemicals that are polymerically dissolved in a base material. Different types of masterbatches include colored masterbatches, filling masterbatches, reinforcing masterbatches, anti-UV masterbatches, etc.

The types of masterbatches are:

1- Colored masterbatches

A color masterbatch is a color concentrate used to color plastic products. This product is produced by combining a base polymer, pigments, and other additives. In simpler terms, a color masterbatch is a color that is granulated and added to plastic to give it the desired color. These colors can be shiny, matte, fluorescent, etc., and give the base material more aesthetic and attractive properties.
A color masterbatch usually contains a high percentage of pigments and a lower percentage of the base polymer. To be effective, the masterbatch polymer base must be compatible with the main polymer that is to be colored. This compatibility allows the pigments to be well distributed in the final product.

2- Additive masterbatchs

Additive Masterbatch is a concentrated mixture of additives dispersed in a polymer carrier, used to enhance the properties of plastic products during manufacturing. Unlike color masterbatch, which focuses on adding color, additive masterbatch is designed to improve the functional characteristics of plastics. These materials can include the following:

1. Stabilizers:

They are used to increase the lifespan of plastic and prevent its degradation due to environmental factors such as sunlight, heat and chemicals.
2. Antioxidants:
They are used to prevent plastic oxidation and yellowing.
3. Lubricants:
They are used to reduce friction in the plastic production process and improve the surface quality of plastic products.
4. Flame retardant materials:
They are used to increase the fire resistance of plastic.
5. Anti-UV materials:
They are used to protect plastic from UV rays and prevent its destruction.
6. Antibacterial substances:
They are used to prevent the growth of bacteria on plastic.
7. Slippery materials:
They are used to improve the plastic production process and prevent plastic from sticking to devices.
8. Deodorant materials:
They are used to absorb unpleasant smells from plastic.
9. Clarifying agent for plastic:
They are used to increase the transparency of plastic.

3- Filler masterbatches

Fillers are mineral or organic materials that are added to plastic and reduce cost, increase productivity, improve properties, etc. Common fillers include calcium carbonate, talc, barite, and glass fibers.

4. white masterbatchs

White Masterbatch is a polymer additive used to create white color and increase brightness in plastic products. This material is produced in granular form and added to the base polymer during the plastic production process. White Masterbatch is an economical and efficient option for whitening plastics due to its high concentration of titanium dioxide (TiO₂), the most common pigment used in white masterbatch. This material is the best option for creating whiteness and brightness due to its high covering power and resistance to environmental factors.

White masterbatch are perhaps the most popular masterbatch on the market. For more information, you can read the article Introducing White masterbatche.

5. Black masterbatch

Black Masterbatch is a polymer additive used to create black color in plastic products. This material is produced in the form of granules and is added to the base polymer during the plastic production process. Due to the use of carbon black pigments, black masterbatch not only creates a black color but also improves properties such as UV resistance and electrical conductivity. For more information, you can read the article what is black masterbatch.

Masterbatch production process

Masterbatch production is a precise and controlled process that involves combining polymer base materials, dyes or additives, and other auxiliary materials. This process is usually carried out in several main stages, as follows:
1. Selection of raw materials
2. Weighing
3. Mixing
4. Extrusion
5. Cooling and cutting
6. Packaging and storage
In the masterbatch manufacturing process, the ratio of raw materials must be carefully observed to ensure the quality of the masterbatch. At each stage of production, samples are tested to ensure the uniformity and proper functioning of the masterbatch. Extruder and mixer machines must be of high quality to optimize the production process.
Masterbatch production is a complex and specialized process that requires technical knowledge and specialized equipment. By observing the correct production stages and using quality raw materials, masterbatches with desirable properties and applications in the polymer industry can be produced.
