What are the uses of white and black masterbatch?

In the polymer processing industry, many types of masterbatches are used for manufacturing plastics. The plastic processors face a daunting task of meeting the expectation of customers with colour, features and properties to make commercially viable products. It is where the quality masterbatches play significant roles to manufacture plastics with suitable characteristics and properties.

How do masterbatches help in plastic processing?

Masterbatch is a solid or liquid material used in imparting colour and functionalities to a base polymer. The polymer additive comes in a pellet or liquid form to use with a base polymer to deliver the right tone and other features. A processor must choose a compatible additive based on a base polymer to improve processability and properties in the yielded product.

Besides imparting vibrant colour to consumer products, masterbatches play roles to improve performance in processing to deliver consistent quality plastics. Some of the additives work to enhance colour dispersion, processability, develop essential properties such as durability, strength and other mechanical properties. Hence, companies need to test the sample before using polymer additives in processing for a reliable result.

Black masterbatch

Black masterbatch is one of the most popular additives in the polymer processing industry. It is made of 50% in its composition. The black pigment has many applications in the plastic industry. The primary use of this additive is UV protection, jetness, conductivity and dispersion during processing. However, the preference for this additive is taken based on surface areas that get increased, which decreased in particle size. The processes on which black masterbatch used are injection moulding, blow moulding, monofilaments and HDPE pipes.

Uses of black masterbatch

Using black masterbatch has many benefits in industrial applications. Here are the top benefits of this additive:

• Superior dyeing at a low dosage level.
• Enhance mechanical properties to prevent wear and tear while giving a higher stiffness.
• Compatible with the packaging of food items.
• Give superior result in the stretching.

Industrial applications of black masterbatches

• Automotive
• Agriculture
• Electronics
• Shoes
• Packaging
• Fibers
• Electrical products

White Masterbatch

The white masterbatch is another popular additive in the processing industry. The additive is made of Titanium Dioxide where loading can go up to 75%. The filling of the Tio2 defines the brightness, whiteness and transparency of the products. The average particle size is 0.19 to 0.22 micron to get high refractive index and opaqueness of a product. The standard uses of white masterbatch are lamination, extrusion coating, protective films, injection moulding, fibre and non-woven products.

Industrial applications of the white masterbatch

The WB is used in the following industrial applications:

• Agriculture products
• Home appliances
• Packaging of food items and others.
• Textile and fibres

Manufacturing quality masterbatches require research and development with excellent infrastructure for companies. Hence, a plastic processor needs to look into these detail before purchasing polymer additives from a manufacturer.

Conclusion

Masterbatches play numerous roles in the polymer processing from imparting colour to mechanical properties. But, it is essential to listen to consumer demand in the market to adopt them in plastic manufacturing.
