Significance of masterbatches in polymer processing

Plastics are ubiquitous. Various materials are made of plastics, from mobile phones, packaging, automotive accessories, construction materials to everything that is in use in everyday life. The modern lifestyle depends a lot on plastic usages, which come in various forms, shapes and benefits for consumers.

The popularity of plastic products shot up due to their super flexibility, resilience, waterproof, and other versatile natures. Polymer products are not only wide produced but used almost worldwide. Thus, plastics are popular and became an integral part of the material world.

Giving life to plastic products

The plastic processing industry is worth billions in the market now. The sector is expected to grow even faster in the coming years, despite some environmental concerns and problems. However, chemical engineers are doing research and development to find eco-friendly alternatives.

Polymer processing is complex. The process imparts properties to a raw polymer during the processing. A raw polymer gets many properties such as stiffness, strength, colour, and other features during the processing. Processing the natural polymers could be possible with the use of a variety of masterbatches. Manufacturers decide to use a masterbatch based on the features and properties required in the finished properties. Hence a processor needs to know the top polymer additives and their impacts on plastics.

Types of masterbatches and their significance in polymer processing

Consumers demand plastics with beautiful colour, design, shapes and properties. Processors make the plastic more appealing with the incorporation of colourant in the processing. Further, new properties and features come in plastic with the use of masterbatch.

Here are the types of masterbatches and their uses in processing:

Colour masterbatch

Plastics come in a variety of colours such as red, blue, yellow, silver, and other hues in the market. Many masterbatches act as a colourant to impart the desired shade to a polymer during the manufacturing process. The primary use of a colour masterbatch is to give the desired hue to a product.

Additives

Many masterbatches work beyond colouring the base polymer in the manufacturing. They change the mechanical properties and features of a yielded product. The appealing feature of smooth surface, gloss, strength, and other mechanical properties come while processing with an additive. The additive further enhances processability of a base polymer in the manufacturing. It can act as a slipping agent, antimicrobial, anti-fog, and others. The BOPET masterbatch is an excellent example of an additive that acts as a slipping agent in the manufacturing process. It can accelerate the manufacturing process for the higher productivity and output of a company.

Special effect masterbatch

The special effect masterbatch provides polychromatic and holographic colour effects on plastic products. The result of a rainbow and colour spectrum in plastic comes with the use of this masterbatch during the processing.

Advantages of using masterbatch

Over the years, plastic properties and manufacturing costs have declined, which has increased the profits of companies. Raw polymers are cheap and easy to process with the right additive in the manufacturing. Here are some of the advantages of using masterbatches:

• Add colour and other physical properties.
• Enhance product stability and appeal to masses.
• Help to produce products with consistent quality.
• Cheap products for consumers.
• Masterbatch enhances the profitability of plastic manufacturers.

Conclusion

Polymer additives are significant to produce plastics with consistent quality for consumers in the market. The processing of polymers has become convenient due to the presence of quality additive such as the silicone masterbatch, which is a slipping agent in plastic manufacturing.
