What is a masterbatch and its role in plastics processing?

Plastics are common materials with vast usages in the modern lifestyle. We can find plastics in packaging, consumer products to construction and automobile accessories. There is no sector which didn’t get the impact of the polymers. Thus, polymeric products are ubiquitous and have become an integral part of the modern industry.

Plastic processing industry

The plastic processing industry is growing at a rapid pace around the world. It is already billions dollar industry, and adoption of advanced technology is set to bring more future growth.

There is one reason for the growth of the polymer industry is the satisfaction that customers get in using them. The raw polymer is versatile and can be moulded into different shapes with the use of the right technology. The revolution in plastic processing is taking place due to the masterbatch.

What is a masterbatch?

Masterbatch is a solid or liquid material used to impart colour to the base polymers. The raw polymers don’t contain any colour or distinctive features. It is by processing with the masterbatches the plastics get its physical and mechanical properties.

The white masterbatch is an example of colour masterbatch. Apart from adding colour, the additive influence changes in plastic physical and mechanical properties. But, the selection of a masterbatch depends on the essential features needed in a product. In this way, the features to come in a final product is decided for a process.

Here are the three types of masterbatch used in the plastics processing industry:

l  Colour masterbatch

l  Additive

l  Special effect masterbatch

Each of these performs a distinctive function in the processing of the polymeric products. However, everything is designed based on the requirement of a customer.

The additive brings new functionalities and physical properties in addition to imparting colour to a product. But, the special effect additive helps in increasing the output of products in the plant.

Most importantly, some of the polymers perform dual functions acting as the pigment and alter functions of the product. The black masterbatch offers blackness to products while improving the property of electrical insulation and lustre. Thus, it has become a crucial additive for plastic processors around the globe nowadays.

What are the uses of black masterbatch in plastic processing?

Black masterbatch is one of the most popular additives used in the plastics processing industry. The additive plays a significant role in the manufacturing processes like injection, moulding, extrusion moulding, and blow moulding. All these processes are essential to make many commercial plastic products like pipes, automotive accessories, agriculture fill and geotextile materials in the industry.

What are the significant uses of black masterbatch?

The primary role of an additive is to add colour, that is to enhance the blackness of a product. In the polymer industry, this masterbatch has two roles acting as a colourant and maintain chemical stability of the pigment.

The benefits of using this additive in plastic processing: 

Uniform distribution of pigment

Owing to its excellent dispersion, it makes the distribution of pigment in the product equal. The quality of the masterbatch can be further refined to enhance the uniformity of pigment distribution in the products. Hence it is an excellent colour dispersant which helps in dispersing colour evenly in the products.

Maintain chemical stability of pigment

Owing to the higher chemical stability of the pigment, storing of black masterbatch for a longer-term without losing any property is possible. While using, it inevitably comes in contact with air which appears to form water, oxidation, and other phenomena may occur. However, the additive remains stable even in the storage for a long time.

What are the unique properties of black masterbatch?

In addition to the above benefits, black masterbatch has excellent compatibility and show its effects on various products. It has a significant impact on the plastic on using during the processing. Here are some of the effects that you will get:

• Offers excellent blackness to the products.
• Provide insulation to polymer products.
• Offer thermal stability.
• UV protection on products.
• Heat dissipation.
• And others.

Thus, it is not difficult to see why it has become a popular choice for plastic processors around the world. The range and composition of carbon black are decided based on the effects needed in the plastics.
