Gold color masterbatch
PP masterbatch is a high concentration of the dye, which is made of pigment, carrier, additive three parts. Its mainly used for carpet, filament, and other products coloring. What are the advantages of polypropylene masterbatch it? Here's a detailed look at it:

01
Coverage is stronger
The first factor in determining the quality of a dyeable masterbatch is the covering power, which is particularly important for masterbatches used in waste or recycled polymers, where the effect of black is to cover the waste Of the other colors. Large particles of carbon black coloring ability is poor, not easy to cover all the other colors in the lower layer, the results of the final product only get the color deviation. The ability to correctly select a carbon black with a high coloring ability to cover the existing color during the melting process is called a covering force.

02
Liquidity is better
The second factor determining the quality of dyeable polypropylene masterbatch is rheology and fluidity. If a masterbatch itself has good dispersion, but it can not flow into the material to be molded, the production effect is not ideal. In general, the base resin used to produce the masterbatch has a high rheology. In order to save costs, some masterbatch producers use recycled materials, scrap or recycled materials as resin carriers. The flow properties of the masterbatch thus produced will be significantly reduced, and if the rheology is not good, the moldmaker will have trouble in handling the cycle time and appearance. It is noteworthy that, if the dispersion and rheology is not high, some end users will increase the dilution ratio to make up, but this approach will only increase the use of masterbatch cost. The masterbatch with the smallest dilution ratio produces homogeneous, well-dispersed blacks.

03
Compatibility to be large
The third factor determining the quality of polypropylene masterbatch. If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other non-meltable polymers. This will cause some unpredictable, difficult to restrain the trouble, wasting the time and raw materials of the final consumer. At this time, you can use primer resin to produce high-quality masterbatch, masterbatch in the melting process have a good compatibility. High quality masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials. If engineering grade and strict physical properties have been specified, then special polymeric masterbatches may be obtained. Several large international masterbatch producers are conducting research to produce so-called "universal" masterbatches. These masterbatches can be used in a wide range of other raw materials, with good rheology and flexibility.

04
Stability should be consistent
In today's international economy, the international customers of the masterbatch quality, raw materials, such as the stability of the high performance is absolutely necessary, which is the quality of the decision of the black masterbatch of the fifth factor. One of the main manifestations of stability is the proportion of smooth carbon black. If the percentage of carbon black is fluctuating, the amount of masterbatch to be melted is not the same and it is not possible to produce a product of the same color. Some final producers report that the dilution requirements are usually between 5 and 8 percent, depending on the amount of material that the masterbatch manufacturer has put into the manufacturing process. Obviously this is unacceptable. Of course, other factors such as the fluidity and dispersion of the injected melt should be consistent with the feed rate of each batch.

05
Brightness to be clear
The final factor determining the quality of the dyeable masterbatch is the shade of the color. There are various types of carbon black on the market can be used for color masterbatch, but all kinds of colors and prices are very different. The large particle carbon black has a lower coloring degree and a different background color than the small particle carbon black. Large particle masterbatches are suitable for the production of films such as garbage bags, but are not suitable for the production of aesthetic-oriented products such as television signs or areas requiring UV protection such as agricultural films or external pipelines. For these products, only the use of high-priced small particles of carbon black. In addition, low transparency is also a characteristic of small particle carbon black.
