Plastic black masterbatch is produced using carbon black. We mainly analyze the factors that determine the quality of plastic black mother for you, as follows:

A. Stability:

In today's internationalized economy, it is absolutely necessary for international customers to have high requirements on the quality of masterbatches and the stability of raw materials. This is the fifth factor that determines the quality of black masterbatches. A major manifestation of stability is a smooth carbon black ratio. If the percentage of carbon black is fluctuating, the number of masterbatches that need to be melted is not the same, and it is not possible to produce products of the same color tone;

B. Dispersion:

Raw carbon black is a very difficult and dirty mixture. It is dusty, light and fluffy. Unless large-scale treatment measures are used, it will stain machines and workers and make the working environment dirty

C. Rheology:

If a masterbatch itself has good dispersion, but it cannot flow into the material to be molded, the production effect is not ideal. Generally, the primer resin used to produce masterbatches has a high rheology. In order to save costs, some masterbatch producers use recycled materials, waste or recycled materials as resin carriers;

D. Color brightness:

There are various types of carbon black on the market that can be used to color masterbatches, but the colors and prices of each type are also very different. Large particle carbon black has lower coloration and different background color than small particle carbon black. Large grain black

Masterbatches are suitable for the production of films such as garbage bags, but they are not suitable for the production of aesthetically-conscious products, such as television signboards or places that require UV protection such as agricultural films or external pipes.

E. Coverage:

This factor is especially important for masterbatches for waste or recycled polymers, where the role of black is to cover other colors in the waste. Large particle carbon black has poor coloring ability, and it is difficult to cover all other colors in the lower layer. As a result, the final product has only deviated colors. In the melting process, the ability to correctly select the carbon black with high coloring ability to cover the existing color is the so-called covering power;

F. Compatibility:

If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other non-meltable polymers. This will cause some unpredictable and difficult to restrain the trouble, and waste the time and raw materials of the end consumer. At this time, a primer resin can be selected to produce high-quality masterbatches, and the masterbatches have good compatibility during the melting process. High-quality masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials;
