White Masterbatch- outstanding quality and most effective method for plastic products.

Masterbatch is not a new thing in the world of the plastic industry. Firstly, the mixture of pigments and additives is heated and converted into a carrier resin which again is cooled down and cut into granules. The plastics get the color and properties from masterbatches. As the solvent in the polymer of the masterbatches doesn’t evaporate easily, that is why they tend to have a longer shelf life. There are many masterbatches in the industry, below are the details about one of the most prominent ones in the Masterbatch category. Particularly, I will illustrate White Masterbatch one of the most popular masterbatches in the world, and its applications in the plastic industries.

1. What is white masterbatch?

White Masterbatch is a type of color masterbatch, which is made of Titanium Dioxide (TiO2), plastic resin, and other additives. It is used to improve the opacity, whiteness and glossiness of plastic end-products and is specifically suitable for the blown film, extrusion blow, injection molding, and other products. Depending on end-products requirements, Us Masterbatch White Colorant contains from 10% up to 80% TiO2 pigment.

2. What are the features of White Masterbatch?

White Masterbatch have the various characteristics and properties for a plastic manufacturer such as:

• One of the most important for white masterbatch to be overweight than other products is the very high level of resin and TiO2 disperse, it appears a stricter and higher requirement than other materials because it is applied to almost resin based.
• Besides the TiO2 disperse properties, White masterbatch is a non-toxic material, that is the reason why it is a very popular material in producing skincare items, food packaging products,….
• Formerly, manufacturers often use Carbon dioxide as the direct material in product to color products, however, this activity often makes the working environment very dusty and populated. For that reason, the white masterbatch is invented to deal with that problem and increase the dosage in using also.
• This is the most popular method to decorate the bright white color for plastic products.
• White masterbatch can be compatible with many different types of background resins.

 

 

3. What are the applications of White Masterbatch for plastic industries?

Due to the outstanding benefits of White Masterbatch, this material has become the most popular coloring product in the world, it is the best choice in manufacturing packaging film, extrusion, or injection,…

• Packaging film

Some common applications of blow film include shopping bags, garbage bags, roll bags, pharmacies,… By using white masterbatch, film layers are offered great dispersion, a high level of brightness, and UV resistance thus increasing the content protective effectiveness. The high TiO2 disperse and resin is the most important for this application. The customer often requires a very high demand for high dispersion of the film, do not appear any dots on that.

• Raffia

The resins used for this application are mostly PP with various applications such as PP bags, laminated PP bags, a FIBCs (flexible intermediate bulk containers).

This application also has a high demand for resin and Tio2 disperse and especially, a high level of strength, flexibility, and UV resistance to prevent polymer degradation and yellowish effect.

• Injection-molded items

Not only applied for blow film but it is also added to caps and enclosures manufacturing process. They are all complex products, therefore the material in these products need to prevent unexpected shrinkage and warpage and provide outstanding stress crack resistance for end-products. White masterbatch needs to have the melt mass index – ensure the resin and TiO2 disperse of the white masterbatch which is suitable with the resin-based. If it is too low, the end-products face the trigidid wall easily to be broken. Otherwise, it is too high which will make the liquid can not fill all of the molds.

Besides, white masterbatch also enhances whiteness and brightness for other plastic products such as tables, chairs, cans, and bottles,…

• Nonwoven

The widely applied for this industry such as hygiene medicine, non-disposables, diapers, rug,….  The most important thing for choosing the correct white masterbatch that has high heat resistance properties and good Tio2 disperse.

• Agricultural films

Agricultural films or Mulch films are plastic films that are laid at ground level around crops to suppress weed growth, maintain humidity, and protect roots from climatic extremes. White masterbatch is customized based on particular requirements from manufacturers to offer additional benefits such as UV resistance, great Tio2 disperse, and processing stabilization.

• Extrusion

The popular application for extrusion is pipes, white masterbatch becomes the coloring material. It offers great TiO2 disperse ad enhances mechanical properties for end-products such as resistance, weather resistance, and processing ability,…
