In people's lives, the application of plastic materials is ubiquitous, and the colors of plastic products are also colorful. Do you know how plastic products get their color? This is because they add color masterbatch to the products that make plastic.
The definition of color matsterbatch
Color masterbatch refers to the plastic colorant formed by the good dispersion of a high proportion of pigments or additives and thermoplastic resin. The selected resin has good wetting and dispersion effect on the colorant, and has good compatibility with the colored material. Color masterbatch coloring is the most commonly used plastic coloring method. It is widely used in smooth film, film blowing extrusion, injection blow molding, profile and sheet extrusion, injection molding and thermoforming.
The advantages of color masterbatches
Color masterbatches can improve many physical properties of plastics. For example, adding plastic color masterbatch to plastic products can help plastic products obtain higher toughness, adhesion and bending stiffness, etc.
Color masterbatches also allow factories to keep fewer grades of polymer in stock and buy cheaper natural polymers in bulk. Color masterbatches have good film physical properties and have the ability to specifications.
The composition of the masterbatch can add a relatively high proportion of CaCO3 powder, because its higher specific heat of CaCO3 can help manufacturers reduce material costs, so this also means that less energy can be used to run the machine.
White masterbatches
There are many colors of color masterbatches. White color masterbatch can provide the excellent whiteness, optimum opacity, and perfect dispersion. White plastic masterbatch is widely used in smooth film, blown film extrusion, injection blow molding, profile and sheet extrusion, injection molding and thermoforming processes. Whitening masterbatch is a kind of Color Master Batch, usually called plastic colorant. White masterbatch is bright in color and good in whiteness, high coloring strength, good resistance to migration and heat resistance. This is mainly due to the addition of whitening Master Batch whitening agent and titanium dioxide.
Although titanium dioxide and fluorescent whitening agent are both whitening, the whitening mechanism is different. Many white masterbatch manufacturers use the two together to play a complementary role.
The applications of white masterbatches
White masterbatch has good properties and a wide range of applications. The titanium dioxide content in the white masterbatch should be considered when selecting the white masterbatch. They are widely used throughout the thermoplastics industry and can be designed to incorporate various additives such as processing aids, UV stabilizers, slip agents, antiblocking agents, antistatic agents, and more. Plastic white color masterbatch can also be used in many industries, such as pharmaceutical packaging materials, plastic packaging materials, food packaging materials, chemical industry packaging materials and so on. And white masterbatches can also be used in opaque films, multi-layer and single-layer films, high-volume machines and many other products.
In general, this article introduce the definition of color masterbatch and the advantages of color masterbatch. And then this article explain the whitening performance of white masterbatches.
