What is a white masterbatch?

مستربچ سفید

White masterbatch is a concentrated pigment used to color plastic products. It consists of a white pigment such as titanium dioxide and a carrier resin, usually a thermoplastic polymer such as polyethylene or polypropylene. The white pigment is usually in the upper percentage of about 50-60% and the carrier resin makes up the remainder. White masterbatch is used to paint various plastic products such as films (using film grade white masterbatch), fibers, injection molded parts and extruded products such as pipes, profiles and sheets.

White masterbatch is one of the colored masterbatch which is a combination of titanium dioxide (TiO2). By adding these additives to polymers, the color and properties of the product change. The amount of titanium dioxide in the masterbatch can be between 15 and 80%. The price of the masterbatch depends on the percentage of TiO2.

A combination of polymer carrier titanium dioxide and other additives make a quality white masterbatch. To increase the whiteness and transparency of plastic products, it is suitable to use (TIO2). In various industries where plastic is the basic material for the production of all kinds of products, high quality white masterbatch is used because of its good features.
One of the most widely used masterbatch in industries is the white masterbatch. The combination of this masterbatch with polymer changes the color and properties.

The easiest way to prepare white masterbatch is to combine titanium dioxide and create white masterbatch. In fact, after being combined, white titanium is encapsulated under certain conditions, and by being exposed to high pressure and heat, the pigments are cooled and cut after heating.
Titanium dioxide is an excellent and suitable option for packaging and covering the surface, because it has a special background color. Its particle size is medium. Its background color is special. Its reflection has high light.
It is also used in addition to oyster pigment to produce products whose shiny appearance is important on the plastic surface, such as motor oil bottles or shampoo bottles. The reason for using oyster masterbatch is that oyster masterbatch has the ability to absorb ultraviolet rays. As a result, the absorption of this radiation increases the light of the object and makes the surface of the object more shiny. As a masterbatch producer, Hamon Bespar has launched quality products in this field.

Disadvantages of choosing a poor quality masterbatch

Reduced effectiveness: Low-quality white masterbatches may not provide the desired color or performance, resulting in an inferior final product.
Increased production costs: If the white masterbatch is of low quality, it may not be able to produce the required product or may need to be used at higher concentrations, which increases production costs.
Quality control issues: Products like pipes require high quality. And a poor quality white masterbatch can lead to quality control problems, resulting in inconsistent or defective products.
Environmental Impact: Some poor quality white masterbatches may contain hazardous chemicals or pollutants that harm the environment.
Damage to brand reputation: Using low-quality masterbatches can damage a brand’s reputation if the final product is poor or the use of masterbatches is identified.

Preventing contamination of the produced white masterbatch during packaging and handling

To avoid contamination of the produced white masterbatch during packaging and handling, you should do the following:

Clean packaging and handling equipment

Packaging and handling equipment must be thoroughly cleaned and disinfected before use to prevent contamination.

Use suitable packaging materials

The packaging material used should be of good quality and not contaminate the white masterbatch.

Proper labeling

The packaging should be properly labeled to show the contents and any relevant information such as batch number, date of manufacture and expiry date.

Proper maintenance

Packaged white masterbatch should be stored in proper conditions such as a clean, dry and cool area away from any source of contamination.

Correct methods of transportation

The white masterbatch must be handled carefully to avoid any physical or chemical contamination. This includes using clean, dry gloves, avoiding contact with other materials, and using proper handling equipment.

By implementing these measures, you can ensure that the white masterbatch produced is not contaminated during packaging and handling and maintains its quality until it reaches the consumer.

White masterbatch production problems

The production of white masterbatch, like colored masterbatch, is a vital process that requires precision and expertise to ensure the high quality of the products. However, as with any manufacturing process, problems may arise during the production of the white masterbatch that can affect the quality of the final product. In this paragraph, we will look at some of the most common problems with white masterbatch production and ways to overcome them.

Insufficient dispersion of pigments

One of the most common problems in white masterbatch production is insufficient dispersion of pigments. Pigments are responsible for giving color to the masterbatch, and if they are not sufficiently dispersed, the final product will have uneven color distribution. This can be solved by using high-speed mixers that can disperse the pigments evenly throughout the mixture.

Poor melt flow

Another problem that occurs during white masterbatch production is poor melt flow. Melt flow is essential in the production of masterbatches because it determines how much material flows through the molding machine. If the melt flow is poor, it can lead to issues such as incomplete filling of mold cavities or surface defects in the final product. To overcome this problem, manufacturers can adjust the temperature and speed of the compounding process to improve melt flow.


Contamination is also a major problem during white masterbatch production. Contaminants such as dust, dirt or other impurities can negatively affect product quality. This problem can be solved by using suitable filtration systems that can remove impurities from the mixture before processing.

Creating air pockets during mixing

Another common problem in the production of white masterbatch is the creation of air pockets during mixing. Air pockets can lead to problems such as voids or bubbles in the final product, which can compromise its quality. To avoid this problem, manufacturers must ensure that their compounding process is thorough and use equipment capable of processing the material without entrapping air.

Consequently, while various problems can arise during the production of a white masterbatch, there are just as many solutions available to overcome them. Having a complete understanding of the entire production process and applying the right equipment and technology is very important to ensure high quality products. By addressing the issues discussed above, manufacturers such as Hamon Baspar can produce white masterbatches with consistent color, good melt flow, and no contamination or air bubbles.

Advantages of using white masterbatch for the environment

White masterbatch is a very useful and effective additive that is used in the plastic industry to give white or matte color to plastic products. However, the benefits of using white masterbatch go beyond aesthetic appeal. In fact, the use of white masterbatch can have significant benefits for the environment.

One of the main benefits of using white masterbatch is that it can help reduce the amount of plastic waste produced. When plastic products are made using white masterbatch, they are more likely to be recycled and reused. Because recycling white plastic is much easier than colored plastic. In this way, using white masterbatch can help reduce the amount of plastic that ends up in landfills and oceans, a major environmental concern.

Another advantage of using white masterbatch is that it can help reduce the energy and resources needed to produce plastic products. When plastic is colored, it often requires more energy and resources to produce, as more processing steps are required to achieve the desired color. By using white masterbatch, these additional processing steps can be avoided, which can help reduce the overall carbon footprint of plastic production.

In addition to these environmental benefits, the use of white masterbatch can also have economic benefits. For example, the use of white masterbatch can help reduce the cost of manufacturing plastic products, as it eliminates the need for additional processing steps. This could help make plastic products more affordable and accessible to consumers, while lowering production costs for manufacturers.

Overall, the benefits of using white masterbatch for the environment are clear. By reducing the amount of plastic waste produced, saving energy and resources, and reducing production costs, Masterbatch White is a highly beneficial additive that can help promote sustainability and environmental responsibility in the plastics industry.

9 points that you should consider when buying a white masterbatch

خرید مستربچ سفید

White masterbatch has the characteristics of bright and eye-catching color, high color strength, good dispersion, high concentration, good whiteness, strong covering power, good migration resistance and heat resistance, and is widely used in injection molding, molding Air is used. Keep the following points in mind when buying.

1- Whiteness

The whiteness of the masterbatch The white color is mainly provided by the titanium dioxide in the colored masterbatch, and many factors affect the whiteness of the titanium dioxide, including the size, shape, and size distribution of the titanium dioxide particles, the type and content of impurities, and the network of the dioxide particles. Titanium. In general, since the chlorination method has a higher purity of raw material titanium dioxide and less impurity in the preparation process, the whiteness of the titanium dioxide chlorination method is better than the sulfuric acid method. In the real white masterbatch market, many manufacturers of white masterbatch pretend to be titanium dioxide by adding calcium carbonate, barium sulfate and zinc sulfide with equal ash content, in fact, the whiteness of these mineral powders is not comparable to titanium dioxide.

2- Covering power

Covering power is also a very important indicator of white masterbatch. Good covering power means that the pigment has strong coloring power and with a small amount of masterbatch addition, the required color can be obtained. The covering power of white masterbatch depends on the choice of titanium. Compared with the processing technology, rutile titanium dioxide has a smaller and tighter unit network and a larger refractive index than anatase titanium dioxide, so its covering power and UV resistance are better than anatase for use in The same type of rutile titanium. White rutile titanium dioxide masterbatch, titanium dioxide particle size is small, the particle size distribution is narrow, and the good coating power in the masterbatch is clearly wider than the anatase titanium dioxide particle size distribution, and the dispersion performance is poor in the masterbatch. The coating power of ordinary calcium carbonate, barium sulfate and zinc sulfide is not comparable to titanium dioxide.

3- Dispersion

Dispersion has an important effect on the application of titanium dioxide in plastics. In general, the smaller the titanium dioxide particles, the better the dispersion and the higher the coloring power. When the film needs fine print, it is better to use white masterbatch. With excellent pattern transparency dispersion, layering and grain transparency are better, because the microscopic smoothness of the base layer is one of the determining factors for the quality of the printed pattern.

4- The amount of humidity

The amount of moisture in the white masterbatch also has an important effect on the performance of the masterbatch. In general, the moisture content should be controlled below 1500ppm and the exact requirement should be below 600ppm. In the injection molding process, all raw materials are dried before production, and in film production, they are used directly after premixing with the carrier. If the moisture content of the masterbatch is high, it will directly cause the film to tear and may also cause small bubbles. On the film, “crystal point” and other defects, the reasons for the high moisture content of the white masterbatch are influenced by the raw materials selected for the masterbatch and the process.

5- Smell

Some film producers notice a strange smell after using white masterbatches, which is absolutely not allowed on milk films and films that come into contact with food. This is mainly due to the presence of titanium dioxide in the masterbatch in the organic material. It happens if the coating additive is chosen inappropriately, or if the amount added is too high, or if there is a problem with the spreader used in the masterbatch production process.

6- Color selection

Due to the low reflectance of rutile titanium dioxide in the violet region, rutile titanium dioxide has a “yellow” color that makes the color product appear “old”. After adding a small amount of fluorescent whitening agent in titanium dioxide, it can absorb ultraviolet light with a wavelength of 300-400 nm and convert it to a UV light with a wavelength of 400-500 nm blue fluorescence, which can Create a white masterbatch.

7- Fluidity

White masterbatch fluidity can be defined as melt index (MI) low numerical flow difference, high numerical value
Good fluidity: Good fluidity means good processing performance, low machine torque, low energy consumption,
Time: In addition to the need for good fluidity of the masterbatch, it is necessary to pay attention to the fusion index of the masterbatch and the carrier resin, the general principle is that the MI of the masterbatch is higher than that of the carrier resin.

8- Print thermal sealing performance

In most cases, white packaging products require printing and heat sealing. If calcium carbonate is added to the white masterbatch, it will affect the transparency of the printed pattern. Improper or excessive dispersing materials added to the masterbatch also affect heat sealing and thermal sealing.

9- Light stability and weather resistance

White masterbatch generally requires light fastness of 7-8 degrees, weather resistance of 4-5 and temperature resistance of 280 degrees. These requirements mainly depend on the quality of titanium dioxide. Rutile titanium dioxide should be used to meet the above conditions.

Precautions when using white masterbatch

اقدامات احتیاطی هنگام استفاده از مستربچ سفید

  1. To reduce the color difference of the fiber after color matching, the white masterbatch should be diluted and the mixing ratio should be controlled. Filament should not be less than 3% to 10%, short fiber should not be less than 1% to 3%, and monochromatic continuous filament spinning with tricolor equipment, white masterbatch should enter the extruder after mixing, and at the same time, in order to increase Self-melt mixing capability, a mixing device can also be added in the extruder section.
  2. White Masterbatch Mixing Method After the color formula of the dyed yarn is determined, the key to ensure the quality of the product is to spread the white masterbatch evenly in the polypropylene cuts before spinning. There are two special mixing methods. One is the heavy method and the volumetric method, after the white masterbatch is melted in the extruder, it is injected into the polypropylene melt with a small extruder, and it has a very good uniformity.
  3. When choosing the white masterbatch, it should be selected according to the range, the polypropylene color masterbatch can be divided into high concentration grade and low concentration grade, the high concentration grade white masterbatch cannot be used to match the color of the low concentration grade.
  4. The selected white masterbatch should preferably be the product of the same manufacturer, and to reduce costs, white masterbatch with high concentration should be used. White masterbatch pigments can be divided into high, medium and low grades. When matching color, different grades of white masterbatch should be properly selected according to the qualitative requirements of fiber formation. In order to avoid quality changes of the finished fiber due to the different light and heat stability of the pigment, the white masterbatch color that meets the fiber quality requirements and has the same level of light and heat stability should be selected when dyeing.
