Black Masterbatch
What Is Black Masterbatch?
Black masterbatches are a concentrated mix of carbon black, carrier resin, and various additives used to impart the black colouration to various plastic-based surfaces during the production stage. It is an indispensable part of the plastic industry which adds functionality, reliability, and depth to any product. Its biggest advantage lies in its ability to be infused with various additives and other components to deliver custom-built masterbatch solutions.
Advantages of Black Masterbatch
Colouration
The main purpose of black masterbatches is to impart black colour to the end product. This is done on a wide range of applications where the desired colour is black. Automobiles, electronics, construction materials, and consumer goods all use black masterbatches depending on the product specification.
UV protection
Black masterbatch can be infused with UV-resistant additives to prevent degradation of the polymer matrix due to prolonged exposure. UV stabilisation helps in maintaining the structural integrity of the item especially if it is exposed to the elements of nature continuously. Construction materials are used under such conditions where UV stabilisation is a must.
Heat reduction
Usage of black masterbatch can improve thermal conductivity, thereby dissipating heat build-up more effectively. This is particularly important in cases where heat levels need to be managed at all times, such as electrical devices.
Opacity
Black masterbatches offer solid opacity, allowing them to conceal anything along with any imperfections in the material. It is particularly important where the visual appearance of the final product determines its brand value.

Application of Black Masterbatch
Automotive compounding
As you may not know, automotive is the largest end-use industry for black masterbatches market. Since plastic has gradually come into use in the automotive industry with a view to decreasing overall weight and cutting down on production cost, the demand for black masterbatch is growing rapidly.
Packaging flms
Another common application of black-color masterbatch is packaging films (such as garbage bags, shopping bag...) thanks to the granular form, it disperses more evenly on the end-products surface. Moreover, manufacturers can easily adjust the formula along with loading rate to make it suit the end-products best.
Pipes and conduits
Pipes, tubing, fencing, deck railing... Are amongst the most common extruded applications of black masterbatches. Not only offers end-products attractive.
Looks, it also assists in creating a protective layer, which prevents chemicals from deteriorating end-products' surface as well as enhancing their impact strength and wear resistance.
Geomembrane industry
The geomembrane industry has traditionally used pre-coloured compounds but more and more geomembrane manufacturers are adding masterbatches to the virgin resin. The role of the masterbatch and carbon black is to provide optimum uv and thermal protection of the membrane. As carbon black is one the most effective and most widely used light stabilizer for plastic materials, it is commonly embedded into masterbatch to improve the uv resistance ability of geomembrane.
Recycled black masterbatch for various applications
With a view to delivering cost effectiveness, a new line of black masterbatches that contain 100% recycled content has been introduced. It is said to be made of 100% recycled carbon black from post-consumer tires and polyethylene (pe) resin from a recycled stream, thus helping manufacturers save costs as well as achieving the same performance as many standard grades of carbon black.

Black Masterbatch Production Process
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.
Black Masterbatch：Mastering the Use
Proper dosage
Determine the optimal dosage of masterbatch required to achieve the desired black coloration without compromising other properties of the plastic product.
Uniform dispersion
Ensure thorough dispersion of the masterbatch within the polymer matrix to avoid streaks or inconsistencies in color.
Compatibility
Select masterbatches that are compatible with the base polymer to prevent issues such as poor melt flow or degradation.
Testing and optimization
Conduct thorough testing to evaluate the performance of the masterbatch under various processing conditions, and optimize formulations as needed.
Storage and handling
Store masterbatches in a cool, dry environment away from direct sunlight, and handle them with care to prevent contamination or degradation.
Technological Advances in Black Masterbatch
Nano-black masterbatch

Eco-friendly formulations
With growing environmental concerns, there is a shift towards eco-friendly black masterbatch options. These formulations use recycled materials and biodegradable carriers, reducing the environmental footprint of plastic products.
High-performance additives
Modern black masterbatch products often include high-performance additives that enhance the uv resistance, thermal stability, and mechanical strength of plastics. These additives ensure that the final products meet stringent quality and performance standards.
How to Solve the Uneven Coloring of Black Masterbatch
Dry the material
If it is moist, it will melt at the mouth first, but it is not completely melted, so it will be squeezed there and not go down, and the sun-dried material is easier to enter than the wet material.
Reduce the temperature of the material opening
Or even drop it very low, such as 100 °c, so that the material is not melted before entering, but is directly squeezed in, relying on the power of the screw, not the heat. The disadvantage of this method is that it is made for a long time, and the damage to the screw is relatively large.
Use the broken screw to do it
And replace the diameter of the front section slightly smaller than the back, the gap is larger, and it is easy to feed.
Enlarge the inlet
If you are doing this for a long time, you can cut the inlet larger. Of course, large cutting does not mean that you can feed more, you can install mixing equipment, you can refer to the production equipment of PS foam powder.
Replace the disc of the motor
Change the diameter of the rotating disc to large, so that the screw speed is accelerated, and the disguised phase stirs it in when the material has not yet dissolved. The disadvantage is that the screw is easy to stir, you need to be more cautious, and after the speed becomes faster, the temperature should be adjusted up in the heating zone behind, otherwise the carrying force of the screw is too large.
Process of Black Masterbatch
Mixing the pigment and additives
The first step is to mix the carbon black or other black pigments with additives such as dispersants, antioxidants, and processing aids.
Compounding
The next step is to compound the pigment and additives mixture with the carrier resin, typically a polyethylene or polypropylene resin.
Extrusion
The compounded mixture is then fed into an extruder, where it is melted and mixed thoroughly to ensure a consistent dispersion of the pigments and additives.
Pelletizing
The melted mixture is then pelletized into small, uniform pellets that can be easily transported and stored.
Black masterbatch is a highly specialized product that requires careful attention to detail during the manufacturing process to ensure consistent quality and performance. As a manufacturer of color masterbatch, producing high-quality black masterbatch can be a valuable addition to your product lineup.
The Quality Factors That Determine The Black Masterbatch
The black masterbatch is produced using carbon black. The performance of carbon black, which is difficult to disperse, has been plagued by color masterbatch manufacturers. The high-load black masterbatch produced by single or double screw extruder has very poor dispersion. When the end user mixes or molds these black masterbatch, its performance is only slightly better than carbon black, but the effect is also unsatisfactory. In order to achieve a stable high dispersion, a high-level shearing machine must be used to mix carbon black, such as a mixture of fcm or banbury. With sufficient strength, these mixers can completely mix carbon black and base resin together. The type of carbon black used also affects the color dispersion. The smaller the carbon black particles, the more difficult the dispersion.
The second factor that determines the quality of the black masterbatch is the covering power. This factor is especially important for the masterbatch used for waste or recycled polymers. In these cases, the role of black is to cover other waste materials. Colour. The coloring ability of large particles of carbon black is poor, and it is not easy to cover all other colors in the lower layer. As a result, the final product only gets the deviated color. In the melting process, the ability to correctly select carbon black with high coloring ability to cover the existing color is the so-called covering power.
The third factor that determines the quality of black masterbatch is rheology and fluidity. If a masterbatch itself has good dispersion, but it cannot flow into the material to be molded, the production effect is not ideal. Generally speaking, the base resin used to produce masterbatch has high rheology. In order to save costs, some masterbatch manufacturers use reusable materials, waste materials or recycled materials as resin carriers. The flow properties of the masterbatch produced in this way will be significantly reduced. If the rheology is not good, the mold union will encounter trouble in cycle time and appearance processing. It is worth noting that if the dispersion and rheology are not high, some end users will compensate by increasing the dilution ratio, but this approach will only increase the use cost of the masterbatch. The color masterbatch with the smallest dilution ratio can produce uniform black with good dispersion.
Compatibility is the fourth factor that determines the quality of black masterbatch. If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other infusible polymers. This will cause some unpredictable troubles that are difficult to restrain, and waste the time and raw materials of the final consumer. At this time, the base resin can be used to produce high-quality masterbatch, which has good compatibility during the melting process. High-quality masterbatch can be produced using lldpe, ldpe, hdpe, pp, ps, san, pa and other materials. If engineering grade and strict physical properties have been indicated, then special polymer masterbatch can be obtained. Several large international masterbatch manufacturers are conducting research to produce the so-called "global universal" masterbatch. These masterbatches are widely compatible with other raw materials, have good rheology, and can be used flexibly.
The final factor that determines the quality of the black masterbatch is the brightness of the color. There are various types of carbon black on the market that can be used for the coloring of masterbatches, but the colors and prices of various types are also very different. Large particle carbon black has a lower degree of coloration and a different background color than small particle carbon black. Large-grain masterbatches are suitable for the production of films such as garbage bags, but not for the production of products that focus on aesthetics, such as TV signs or places that require UV protection, such as agricultural films or external pipes. For these products, only high-priced small particle carbon black is used. In addition, low transparency is also a characteristic of small particle carbon black.
