Masterbatch is a concentrated compound that uses polymeric materials as the basis of its formulation. It contains three components of a polymer base, additive chemicals, and an active compatible agent as a dispersant. Masterbatch has a lot of extra ingredients; But these substances are usually pigments, mineral fillers, or chemicals. The reason for using more of these materials in the preparation of masterbatch is the production of paint, improving the properties, or reducing the cost of polymeric materials. The masterbatch polymer base usually has to look like injected plastics, so it looks like a bead. These grains, called granules, can be used in injection molding machines. In the continuation of this PETROPROVIDERS article, join us to show you Masterbatch applications.

Masterbatch components and features

Masterbatch components

Masterbatch components

This is one of the most important materials used in global industries. Masterbatch applications are very diverse; Because this material has the following ingredients:

Base polymer

These materials are usually in the form of “polyethylene, polypropylene, polystyrene, ethylene-vinyl acetate, low molecular weight vaccines, alkyd polymer or polymer” materials.


Factors that change the chemical properties are additives; So their importance is irresistible. Some of these ingredients are: “Properties-enhancing additives, pigments, and fillers”. The amount of input of each of these materials is determined depending on the volume and quality of work and is different in each masterbatch.

Compatibility factor

The best way to spread the paint is to combine it with molten polymer and be compatible with the final material used.

Introducing Masterbatch applications and their types

Masterbatch is divided into different types. Different grades of this material have different uses.

Color Masterbatch

The most common method of producing colored parts is from plastic materials, and the best way to do this is to add color masterbatch. These additives sometimes, in addition to creating the desired color, improve and modify the physical and mechanical properties. Color masterbatch has different definitions; But in its most basic form, a plastic mixture contains a high percentage of pigment.

Of course, we also add a small percentage of polymer to it, and this is how the concentration and amount of this substance lead to different samples. Types of masterbatch are: “color masterbatch, white masterbatch, black masterbatch, and other colors”.

These materials usually have two types of stabilizers and two types of internal and external lubricants, which are called pigments and polymer bases. With the help of masterbatch, the desired plastic can be made in different colors.


  • Nano: Nano masterbatch is commonly known as PE, PP, and UPVC and its main use is to improve mechanical properties and impact resistance.
  • Clarifier or nucleator: This class increases the transparency of polypropylene through molecular organization during the process. This property in most materials also leads to double transparency of the product.
  • Lubricant: The layers of film produced are usually difficult to separate, and this can cause many problems for the production line staff. For example, in the production of some medical equipment and supplies, such as syringes, the friction between the two parts slows down its movement. Therefore, Masterbatch is the solvent of these problems.
    This Masterbatch causes better slip and reduces the adhesion of the product surface to metal parts. Types of this product include “polyethylene base for use in nylon, Nylex and multilayer films and polypropylene base for cellophane”
  • Anti-block: Anti-block is used in the production of polymer films. This additive is used to reduce the adhesion of film surfaces to each other after production until consumption.
  • Brightener: This masterbatch is used to shine and remove the opacity of products, and due to the passage of more light in the product, it gives more polish to plastic products. This material is used in ordinary, thin, and thick films, disposable containers, and all kinds of plastic products.
  • Antistatic: The most important uses of this type of masterbatch are to prevent static electricity generation and dust absorption.
  • Light stabilizer: Prevents the destructive effects and discoloration of polymer products exposed to ultraviolet radiation. The biological aspects of this type of masterbatch have also attracted the attention of physicians. This can lead to the use of masterbatch structures for pharmaceutical products with different raw materials.
  • Antioxidant: One of the most important damage that any polymer can suffer is oxidation. These masterbatches are used to stabilize the polymer against oxidation factors in the production process.
  • Polymer process aid: They are widely used in the plastic industry to increase extrusion capability. These categories eliminate melt failure, reduce the accumulation of mold heads, and improve the film surface by eliminating the “fish shell” phenomenon. Finally, by reducing the amount of gel produced, they increase the number and circulation of a product.
  • Anti-wear: Polyethylene-based silicone masters are used to improving abrasion resistance.
  • Secondary examples: “Fire-retardant, anti-fog, cleaner, adhesion control, foaming, anti-adhesion, desiccant, flame retardant, paper, shell, biodegradable, antimicrobial, impact-resistant and phosphorescent”.

The main components of color MasterBatch and Masterbatch applications


They are mostly composed of pigments in two groups: organic (such as green phthalocyanine) and mineral (such as red iron oxide or titanium). Some of them, like ink or paint, are ineffective and generally cannot be used to color polyolefins.


The presence of an adapter causes wettability on the surface of the pigment, resulting in better pigment dispersion. It also increases its stability without affecting the quality of the polymer. In most projects, a polymer product is added for greater consistency.

Raw polymer

This polymer uniformly distributes the pigment and facilitates its granular formation. The reason for its use is the compatibility of the polymer, the agent, as well as the greater fluidity of the pigment and the polymer. The polymer, due to its melt index, must be able to dissolve the polymer. Therefore, considering the chemical nature of plastic, the appropriate color can be selected.

Advantages of Masterbatch

By using masterbatches you can save time, energy, and money for mixing and labor. The use of these compounds is economical and due to the lack of proper distribution of some additives, it is not possible to add them directly to the product. Therefore, in the following, we will examine the benefits of Masterbatch applications:

  1. Ease of storage, handling, and use due to its granular shape
  2. Simplify feeding and solve the problem of changing the concentration of the additive and the uniformity of color or properties during production
  3. Masterbatch applications prevent the spread of pigments in the air and thus do not pose a health and safety hazard to employees and do not contaminate adjacent production lines.
  4. Better distribution and uniformity of color, additive, or filler throughout the final product
  5. Use less pigment or additives
  6. Improving the melting process due to the compatibility of the masterbatch binder with the polymer
  7. Masterbatch applications increase the colorfastness of materials!
  8. Better controllability of opacity and transparency of colored products
  9. Reduce feed frequency in the process by using masterbatches containing stable concentrated UV additives, antioxidants, flame retardants, or optical clarifiers
  10. Increase process repeatability by predetermining the ratio of masterbatch additives
  11. Eliminate the cost of cleaning and cleaning
