The compatibility of the black masterbatch is one of the factors that determine the quality of the masterbatch. If the masterbatch is produced using chip or recycled material, it may contain contaminants or other non-meltable polymers. This will cause some unforeseen and difficult constraints, wasting the time and raw materials of the final consumer. At this time, the base resin can be selected to produce high-quality masterbatch, and the masterbatch has good compatibility in the melting process. High-quality masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials.
If engineering grade and stringent physical properties have been noted, special polymer black masterbatch can be obtained. Several international large-scale masterbatch manufacturers are conducting research to produce the so-called “global universal black master batch. These masterbatches can be widely compatible with other raw materials and have good rheological properties. Can be applied flexibly.
The commonly used black masterbatch technique is a wet process. The masterbatch is ground, phase-transformed, washed, dried and granulated in the aqueous phase. Only the quality of the product can be guaranteed. In addition, the pigments should also be subjected to a series of masterbatch techniques, such as measuring the fineness of the sand slurry, measuring the diffusion properties of the sand slurry, determining the solid content of the sand slurry, and measuring the fineness of the colorant. project.
The black masterbatch generally consists of three parts, the colorant carrier dispersant, after mixing, crushing, and squeezing through a high-speed mixer, and the granules are extruded and drawn. The masterbatch has high concentration, good dispersibility, and cleanness in the plastic processing process. And other significant advantages.
