Applications and Features of White Masterbatch in Polymer Processing

Masterbatches are solid or liquid materials obtained by the mixing of colors and additives in a polymer carrier encapsulated through heat treatment. The compounding process of mixing pigment and additives into the base polymer need homogenous merging to be a perfect additive and suitable for the application. The mixture is cooled and cut into granules as a pellet form to use in the plastic manufacturing process. 

The masterbatches come in different features and applications in the polymer industry. However, they are divided based on their applications in the plastic manufacturing process as colorants, additives, and special effect masterbatch. 

Colorants, as the name suggests, are used to add color to the plastic products during the process, and are better than the traditional pigments. The additives add functionalities and features to a plastic product that consumer demand in the market, while special effect masterbatches impart chromatic changes in the final products with their applications. 

White masterbatch 

White masterbatch is one of the most in-demand color masterbatches in the market, second most popular than black masterbatch in terms of market share and application. It is a compound of Titanium Dioxide (Ti02), polymer carrier, and additives merged through the heat treatment. The loading of the Ti02 comes between 20% to 70% pigment, which is added based on the demand and requirement of customers. However, the variance in the pigment loading brings changes in the functionalities and features of final products, making it essential for processors to select the best products for applications. In this way, this masterbatch can be a significant solution to enhance coloration and plastic performance at a low cost. 

The primary function of a white masterbatch is to add whiteness and opacity to the plastic products, and higher loads result in more brightness and opulence. Here are the advantages of using this masterbatch in plastic processing: 

• Enhance the opacity and whiteness of products 
• Provides UV protection 
• Bring thermal stability with reduction of agglomeration of TiO2
• Acts in the anti-fibrillation for woven sack
• Enhance heat resistance
• Increase resistance to weathering condition 
• Suitable for thin film application and packaging 

Applications of white masterbatch 

The application white masterbatch takes place in the manufacturing of various products in the industry. The colorant provides a visually appealing physical appearance packaging while improving the quality of product performance. The packaging materials are durable, smooth, shiny, and can offer better protection to foods and other products in various environmental conditions. Here are the critical applications of this masterbatch: 

• Carrier bags for food and agricultural products
• Packaging materials for shiny products 
• For various manufacturing applications, such as extrusion coating, injection molding, and blow molding

That is why the demand for white masterbatch is rising higher in the market these days to use in different polymer processes and applications. 

Conclusion 

The polymer additive industry is growing at a rapid pace in the world, especially the white and black masterbatch market. The masterbatch is playing a significant role in the production of different plastics for consumers in the market. But, plastic processors must select a suitable additive to get desired functionalities and performance on manufacturing.
