What are the advantages of color masterbatch?

1. Color masterbatch enhances the dispersibility of pigments in products

During the production process of color masterbatch, it is necessary to refine the pigment to improve its dispersibility and coloring power. The carrier of the specialized color masterbatch is the same as the plastic variety of the product, and has good compatibility. After heating and melting, the pigment particles can be well dispersed in the plastic product.

2. Color masterbatch is beneficial for maintaining the stability of chemical pigments

If pigments are directly used in the plastic processing, during storage and use, the pigments will come into direct contact with air, causing water absorption, oxidation, and other phenomena. After becoming the color masterbatch, the resin carrier can isolate the pigments from air and water, which can maintain the chemical stability of the pigments for a long time.

3. Color masterbatch is beneficial for maintaining color stability

Color masterbatch particles are similar to resin particles, making measurement more convenient and accurate. When mixed, they will not adhere to the container and will be mixed evenly with the resin, ensuring the stability of the added amount and thus ensuring the color stability of plastic products.

4. Color masterbatch is beneficial for maintaining the physical properties of the base material

The addition ratio of color masterbatch is low, and the basic raw materials mixed with color masterbatch can be directly injected into the product, which can greatly maintain the physical properties of the basic materials.

5. Protecting the health of operators

Because the color masterbatch is granular, it can greatly reduce the powder flying during the use of pigments, protecting the health of operators.

6.Color masterbatch can ensure the cleanliness of the environment and is convenient to use

Masterbatch is the perfect solution for making plastic products

As mentioned above, one of the most important purposes of using masterbatch is the economic benefits it brings to manufacturers. As early as the early days of the plastic industry, almost all plastic products were made from primary resins, which were directly produced from petroleum and did not contain any other components. However, due to overexploitation, the quantity of natural oil has sharply decreased, leading to a continuous increase in crude oil prices or prices in recent years. In the production of plastic based products, it is strongly recommended to partially replace the original plastic without affecting the original performance of pure plastic.

Compared to powder pigments, if manufacturers use colored masterbatch as a coloring agent for plastics, it will be much easier to store them near the production system without causing cluttered workspace. Employees working in these factories can also easily control the quantity of color masterbatch used and manipulate the entire manufacturing process, thereby minimizing the opportunity to use too many required materials.

Due to the dense and compacted structure of each solid particle, color masterbatch generates less dust during the production process, which helps manufacturers control and eliminate pollution problems inside the factory. During the manufacturing phase, pigments may float into the air, which may cause pollution to adjacent production lines. Compared to traditional dispersed pigment powders, these dust-free color masterbatches not only keep the factory workspace clean, but are also safer and less likely to pose health risks to workers and consumers.

Why use color masterbatch instead of pure pigment?

Pigments are colored substances ground into very fine powders. Adding pure pigment powder to the original polymer is possible, but it is challenging. The challenges include:

Accurately proportioning the ratio of polymer to pigment

Uniformly feed particles of different shapes into a system, including fine powders that are difficult to handle

Uniform mixing of plastic after melting

Some twin-screw extruders are specifically designed for this type of mixing, but are not suitable for wire manufacturing. The simplest strategy is to divide the process into two steps:

Pre mix plastics and pigments to form masterbatch particles. Or purchase pre made masterbatch

Using a single screw extruder to extrude plastics and color masterbatch in particle form

In other words, masterbatch allows you to skip the step of adding pigments and directly use a single screw extruder to manufacture long filaments.

Color paste is similar to masterbatch because they are composed of a medium (water) containing a certain concentration of pigment. However, the color paste cannot be added to the extruder because water can disrupt the extrusion process, disrupt the melting process, and form bubbles in the final filament. Other media, such as oil, are also incompatible with extrusion because they can disrupt friction.

Summary:

Color masterbatch, as a concentrated mixture, provides a convenient and efficient coloring method for plastic products by cleverly incorporating additives into the base polymer. Pigments play a crucial role in color masterbatches, maintaining color integrity and seamlessly integrating into polymer structures through finely ground colored particles. The function of the carrier is to ensure that the pigment is uniformly dispersed throughout the matrix, forming a consistent and uniform color. The application techniques of color masterbatch make plastic manufacturing easier, avoiding some of the troubles and challenges of using pure pigments. Overall, color masterbatch plays an important role in the polymer industry, providing reliable enhancement for the production, processing, and coloring performance of plastic products.
