- The purchased pigment powder has sufficient fineness, which requires more than 1000 mesh.
- The mixing of pigment powder and carrier resin must be sufficient. We use two kneading methods, kneader and internal mixer to ensure a good combination.
- During the extrusion granulation process, add a finer stainless steel filter (between 150 mesh and 180 mesh) to ensure that the coarse particles in the pigment powder are completely filtered out.
- After the manufacture of the masterbatch is completed, the masterbatch is used in the blown film processing process, which can best reflect the dispersion performance of the masterbatch.
