Color masterbatch dispersibility is an important factor for masterbatch manufacturers to ensure the quality of color masterbatch production

1. The purchased pigment powder has sufficient fineness and requires more than 1000 mesh.
2. The mixing of pigment powder and carrier resin must be sufficient. We use two kneading methods of kneading machine and internal mixer to ensure good bonding.
3. During the extrusion granulation process, add a fine stainless steel filter (between 150 and 180 mesh) to ensure that the coarse particles in the pigment powder are thoroughly filtered out.
4. After the completion of the production of the masterbatch, the masterbatch is used for the processing of the blown film, which best reflects the dispersing properties of the masterbatch. This experiment was carried out in the laboratory of the company, and the film with the color masterbatch (about 5μ) was observed. No obvious unmelted particles were observed, and the color of the film was uniform.
