What Is Black Masterbatch for Granulation?
A black masterbatch for granulation is a concentrated mixture of pigments or additives that are used in the plastics industry to color or enhance the properties of plastic materials during the manufacturing process. It is essentially a solid or liquid additive that contains a high concentration of a specific pigment, additive, or filler dispersed in a carrier resin.
Black masterbatch for granulationes are commonly used because they offer several advantages over directly adding pigments or additives to plastic materials. By using black masterbatch for granulationes, manufacturers can ensure consistent coloration and performance characteristics throughout the production process. Black masterbatch for granulationes also simplify the handling and storage of various additives, reduce the risk of dust pollution, and allow for more precise control of dosage levels.
Advantages of Black Masterbatch for Granulation
Improved dispersibility
Pellets solve this problem by providing a pre-mixed composition with the right dispersibility. This ensures uniform coloration and consistent performance enhancements in the final product.
Cost efficiency
Pellets save costs in a number of ways. Manufacturers can keep fewer polymer grades in stock and purchase large quantities of natural polymers at a lower cost. The concentrated nature of pellets allows for greater accuracy when adding expensive additives, reducing waste and overall production costs.
High dilution ratio
Pellets are highly concentrated and have the potential for a high "dilution ratio". For example, 25 kg of pellets can be used to formulate one ton of natural polymer. This dilutive nature makes it ideal for the precise addition of small amounts of additives, improving the cost efficiency and precision of production.
Extended shelf life
Solid pellets contain no solvents, which means they have a longer shelf life compared to liquid additives. There is no risk of solvent evaporation, ensuring that pellets retain their properties for a long time.
Application versatility
Black masterbatch for pellets can be used in most polymer processing methods, making it suitable for a variety of manufacturing processes. Whether it is injection molding, extrusion or blow molding, black masterbatch for pellets can be added to enhance performance and aesthetics.

Factors affecting the Black Masterbatch for Granulation structure
The kind of carrier
The kind of carrier will influence how well the masterbatch and the modified polymer work together. For instance, a masterbatch prepared using a polyolefin carrier will work with polyolefin polymers but not polyester polymers.
The manufacturing process
The structure of a masterbatch can also be impacted by the manufacturing process. In contrast to a masterbatch prepared using a low-shear mixing procedure, one made using a high-shear mixing process will have a more equal distribution of additives.
The kind of additions
The kind of additives will have an impact on the finished product's qualities. For instance, a masterbatch prepared with pigments will alter the end product's color, but a masterbatch made with fillers will alter the final product's weight and stiffness.
The dispersant
The kind of dispersant used will have an impact on how evenly the additives are distributed throughout the masterbatch. A high-quality dispersant will guarantee that the additives are dispersed uniformly, enhancing the end product's performance.
Toner
High-concentration pigments (or dyes) can be used to make special color masterbatches or general-purpose color masterbatches for various plastics; it is also possible to first prepare qualified colors and then mix the pigments with the color masterbatch carrier according to the formula ratio. Through the heating, plasticizing, stirring and shearing action of the granulator, the molecules of the pigment and the molecules of the carrier resin are finally fully combined to form particles similar in size to the resin particles, that is, color masterbatch.
Carrier
The special color masterbatch carrier is the basis of the color masterbatch. Generally, the same resin as the product resin is selected as the carrier, so that the compatibility of the two is the best, but the fluidity of the carrier should also be considered.
Auxiliaries
Mainly include dispersants, coupling agents, compatibilizers, etc. to promote uniform dispersion of pigments and no longer cohesion. The melting point of the dispersant should be lower than that of the resin, and it has good compatibility with the resin and good affinity for the pigment. The most commonly used dispersants are polyethylene low molecular weight waxes and stearates.
Process of Black Masterbatch for Granulation
Ink method
As the name suggests, it is a production method that uses ink colorant in the production of masterbatch, that is, through three-roller grinding, a layer of low molecular protective layer is coated on the surface of the pigment. The ground fine color paste is then mixed with the carrier resin, and then plasticized by a two-roll plasticizer (also called a double-roll open mill), and then granulated by a single or twin screw extruder.
Rinsing method
The pigment, water and dispersant are sanded to make the pigment particles less than 1μm, and the pigment is transferred to the oil phase through the phase transfer method, and then dried to obtain the masterbatch. Organic solvents are required for phase transfer, as well as corresponding solvent recovery devices.
Kneading method
After mixing the pigment with the oily carrier, the pigment is used to make the pigment flush from the aqueous phase into the oil phase by using the lipophilic characteristics of the pigment. At the same time, the surface of the pigment is coated by an oily carrier to make the pigment disperse and stabilize and prevent the pigment from condensing.
How to Choose a Black Masterbatch for Granulation
Colour consistency
Color is so important and here masterbatch plays a major role to give color to the plastic product. Not only color when it comes to masterbatch, shades, and color consistency play a very important role.
High heat stability
Industries like electronics, automotive needs plastic which must have these high heat stability features, that's why masterbatch in plastic must have high heat sustainability so that neither during production there are issues of degradation nor the aesthetic look of the product varies from one lot to other post production.
High light fastness
Like colour consistency and high heat stability, high light fastness is also the main feature of the masterbatch, because this is something which directly leads to the quality of the final product. This is one of the main concerns that need to be properly taken into consideration while choosing a color for plastic. Many fail when it comes to color fading issues once the product is exposed to sun light.
Low moisture content
The moisture content in the masterbatch granules has a great influence on the quality of the final product. In case of high moisture content, the production becomes impossible. Because of this, it is always important to keep eye on the moisture content of the masterbatch to keep expected product quality.Experts of perfect colourants, always take care of this and make sure moisture content must be as low as 0.05%.
Nil migration
No one likes migration; let it be the clothes, country or plastics. Poor quality of pigments used while making masterbatch allows pigment to migrate on the surface resulting into quality rejections. As a company policy, our expert team mandatorily study and uses pigments which are suitable for the application to guarantee nil migration.
High production output
Low pressure built up on the die : Sustainability of any machine is dependent on how it is put to use over the years. Poor quality of masterbatches is responsible for carbon deposition on the screw, barrel and die. This leads to pinholes in the films, low output and wear and tear of the machines in the longer run.
Timely deliveries
In the case of masterbatch, it is always important to deliver the product on time and sometimes even just in time. It is not that easy because it includes factors like small runs, precise colour matching, huge range of pigment inventory, coordination with logistics, swift and low cost transportation to the final location, and eventually safe delivery.
