Masterbatch Quality Identification Method 1
- Sep 05, 2017 -
  1.  High dispersion

  2. Carbon black is a very difficult and dirty mixture that is dusty, light, and fluffy. Unless it is treated on a large scale, it can soil the machine and workers and make the working environment dirty. If the carbon black is directly melted during injection molding, the coloring effect will be very poor. The carbon black type also affects the coloring dispersibility. The smaller the carbon black particles, the better the dispersion.

  3. Strong coloring power

  4. The second factor that determines the quality of the black masterbatch is the coverage. For masterbatches used in scrap or recycled polymers, This factor is especially important. The role of black is to cover other colors in the scrap.

  5. Flexible fluidity

  6. If a masterbatch itself has good dispersibility, but it cannot flow into the material to be molded, the production effect is not satisfactory.

  7. Good compatibility

  8. If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other non-meltable polymers. This can cause some unpredictable and uncontrollable troubles.

  9. Consistent stability

  10. One of the main manifestations of stability is the smooth carbon black ratio. If the percentage of carbon black is fluctuating, the amount of masterbatch to be melted is not the same, and it is impossible to produce products of the same color.

  11. The color shade should be clearly defined.

Large particle carbon black has a lower degree of coloration and a different background color than small particle carbon black. Large particle masterbatches are suitable for film production such as garbage bags, but are not suitable for the production of products that focus on aesthetics
