Getting to know Masterbatch

Masterbatch is one of the polymer products in the plastic industry, which is very important in the production and processing of plastic materials. First, we need to know what is masterbatch? Masterbatch is a concentrated mixture of pigments and additives that are mixed and extruded in a base carrier, such as resin or wax, to add these mixed additives to the final plastic product. These additives may be used for coloring (a color masterbatch) or to improve the properties of the plastic (an additive masterbatch). Most of the colored plastic items that we encounter in our daily lives are painted with masterbatch. Masterbatch is usually supplied in the form of pellets and is combined with raw polymer in the process of producing plastic molds.

Masterbatch is a thick substance that contains an organic or inorganic polymer that acts as a carrier for colors, additives, or cosmetics for plastics. These materials are available as colored polymers, specialty polymers, or reinforcing polymers.

The use of masterbatch in the plastic industry allows the production of plastics with special characteristics. This material greatly simplifies the plastic production process and improves the quality and final appearance of the product.

By using different types of masterbatch, different properties can be added to plastics, including color, heat resistance, UV resistance, fire resistance, etc. This possibility allows manufacturers to produce products with unique features and high quality.

Masterbatch main components

Masterbatch consists of three main components: base polymer, additives, and compatibilizing agent:

Base polymer:
The base polymer of the masterbatch must be similar to the type of plastic to which we intend to add the masterbatch.
Common base polymers in masterbatch include polyethylene, polypropylene, polystyrene, ethylene vinyl acetate, etc.
Additional:
Additives are added to the masterbatch to change the properties of the plastic.
These additives can include pigments, fillers, improvers, antioxidants, lubricants, and flame retardants.
The type and amount of additives depend on the type of plastic, the desired properties, and the final use of the product.
Adapting factor:
The compatibilizing agent is used to create a bond between the base polymer and the additives.
This causes the additives to spread uniformly in the plastic and change its properties favorably.
The compatibilizing agent is usually a polymer with high adhesive properties.

The weight percentage of each of these components in the masterbatch depends on the type of masterbatch and its application.

In addition to the three main components, the masterbatch may also contain other ingredients such as:

Lubricants: To improve the plastic manufacturing process
Anti-UV materials: To protect plastic from UV rays
Antibacterial substances: to prevent the growth of bacteria on plastic

Choosing the right type of masterbatch as well as its consumption depends on various factors such as the type of plastic, the desired properties, and the final use of the product.

Types of masterbatch

Masterbatch is one of the main materials used in various industries for coloring and improving the properties of base materials.

Effective factors in the percentage of masterbatch usage

The percentage of masterbatch usage depends on various factors that can be divided into the following categories:

1. Masterbatch type:

Color Masterbatch:

Generally, 1 to 3% of color masterbatch is sufficient to color the plastic.
Of course, this amount can depend on factors such as the type and intensity of the desired color, the type of plastic and the production method.
Filling Masterbatch:

The percentage of filling masterbatch can be from 5 to 90% (used in disposable tableware).
This amount depends on the type of filler, the desired properties and the final use of the product.
Additional Masterbatch:

The percentage of using additive masterbatch depends on the type of additive and desired properties.
For example, to increase the resistance of the plastic to UV rays, more UV-resistant masterbatch should be used.

2. Type of plastic:

The type of plastic can affect the consumption of masterbatch.
For example, more color masterbatch is needed to dye polyethylene than polypropylene.
This is because polyethylene is naturally opaque and requires more pigment to be dyed.

3. Desired properties:

The amount of masterbatch depends on the desired properties of the plastic.
For example, to increase the resistance of the plastic to UV rays, more UV-resistant masterbatch should be used.
Also, to increase the strength of plastic, strengthening masterbatch such as talc masterbatch or calcium carbonate masterbatch should be used.

4. Final application of the product:

The amount of masterbatch consumption depends on the final use of the product.
For example, to produce clear plastic bottles, less color masterbatch should be used.
The reason for this is that the presence of pigment can reduce the transparency of the bottle.

5. Masterbatch quality:

The quality of the masterbatch can affect its consumption.
Higher quality masterbatches typically require less pigment or additive.

6. Masterbatch price:

The price of masterbatch can affect its consumption.
In general, it is economical to use cheaper masterbatches, but it may reduce the quality of the final product.
