Masterbatch coverage: This is especially important for black masterbatches used in scrap or recycled polymers, in which case the effect of black is primarily to cover other colors present in the waste. The coloring power of large particle carbon black is relatively poor, and it is not easy to cover all other colors in the bottom layer, and the end result is that the product does not achieve the desired result. In the process of melting the masterbatch, correctly select the black masterbatch with high coloring ability can realize the covering power better.

  Rheological properties of masterbatch: If black masterbatch itself has good dispersibility, but it cannot flow into the material to be molded, the production effect is not satisfactory. In general, carrier resin used to produce masterbatches have higher rheology. In order to save costs, some masterbatch producers use recycled materials, scraps or recycled materials as resin carriers.

  Color masterbatch compatibility: If the black masterbatch is produced using chips or recycled materials, it may contain contaminants or other non-meltable polymers. This can cause some unpredictable and difficult constraints, wasting the time and raw materials of the final consumer. At this time, the base resin can be used to produce high quality masterbatch, and the masterbatch has good compatibility during the melting process. Premium masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA, and other materials.

  Color masterbatch stability: In today's international economy, international customers are increasingly demanding higher quality of masterbatch and stability of raw materials, which is also an important factor that decides the quality of the black masterbatch. One of the main manifestations of stability is the smooth carbon black ratio.
