There are several commonly used classification methods for black masterbatch.

Generally speaking, we can classify by carrier, such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch and so on. , and according to the use of classification, such as injection masterbatch, blow molding masterbatch, spinning masterbatch and other varieties can be divided into different grades. Black masterbatch is generally divided into the following categories: 1. Advanced black masterbatch for injection molding: it can be used for plastic packaging boxes of advanced products such as black cosmetics, plastic toys and electrical housings. 2. Ordinary injection black masterbatch: used for ordinary black daily plastic products, industrial plastic containers, etc. 3. Advanced blown film black masterbatch: used for blow-molding coloring of ultra-thin products, such as black plastic bags and black plastic films. 4. Ordinary blown film black masterbatch: used for blow-molding coloring of ordinary black plastic packaging bags and woven bags. 5. Spinning black masterbatch: used for spinning and coloring black textile fibers. The color master batch pigment has fine particles, high concentration, strong coloring power and good light and heat resistance. 6. Low-grade black masterbatch: used for black manufacturing of low-grade products with low requirements on color quality, such as trash cans and low-grade containers. 7. Special black master batch: it is a color master batch made by selecting the same plastic as the carrier according to the plastic variety specified by the user for the product. For example, PP masterbatch and ABS masterbatch are used as carriers respectively. General masterbatch: a certain resin (usually PE with low melting point) is also used as the carrier, but it can be applied to the coloring of other resins except its carrier resin. 8. Universal black master batch: Universal master batch is relatively simple and convenient, but it has many disadvantages. Users are advised to choose special masterbatch. The heat-resistant grade of special masterbatch is generally suitable for the plastic used in the product, and it can be used safely at room temperature. Only under the following circumstances will it cause different degrees of discoloration, one is that the temperature is beyond the normal range, and the other is that the downtime is too long. 9. Compared with particle coloring, black main coloring has the following advantages: 9. 1. Coloring and product processing can be completed at one time, which avoids the heating process of granulation and coloring on plastic and is beneficial to protecting the quality of plastic products. 9.2. Simplify the production process of plastic products. 9.3. It can save a lot of electricity. Because the pigment is in direct contact with air during storage and use, it will absorb moisture, oxidize and agglomerate. When used directly, the surface of plastic products will be stained, the color is dark and easy to fade, and dust will fly when mixed, which will affect the health of operators. In the production process, the color master batch is mechanically processed, and the pigment is refined, and fully mixed with the resin carrier and dispersant, so that the pigment is isolated from air and moisture, thereby enhancing the weather resistance of the pigment, improving the dispersibility and coloring power of the pigment, and having a bright hue. Because the shapes of color masterbatch and resin particles are similar, the measurement is more convenient and accurate, and it will not stick to the container when mixing, saving the time for cleaning the container and the machine and the raw materials used for cleaning the machine.
