The compatibility of masterbatch is one of the factors that determine the quality of masterbatch. If the masterbatch is produced from chips or recycled materials, it may contain contaminants or other non-melting polymers. This will cause some unpredictable and difficult constraints, waste the time and raw materials of the final consumer. At this time, the base resin can be used to produce high quality color masterbatches, which have good compatibility in the melting process. High quality masterbatches can be produced with LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials.

Special aggregated black masterbatches can be obtained if engineering grade and strict physical properties are indicated. Several large international producers of masterbatches are studying to produce so-called "universal black masterbatches globally". These masterbatches can be widely compatible with other raw materials, have good rheological properties and can be used flexibly. The commonly used black masterbatch technology is a wet process. Colour masterbatch is prepared by water grinding, phase inversion, washing, drying and granulation. Only in this way can the product quality be guaranteed. In addition, a series of color masterbatch technology tests should be carried out when the pigments are grinded, such as determining the fineness of the mortar, determining the diffusion performance of the mortar, determining the solid content of the mortar and determining the fineness of the color slurry.

Black masterbatch is generally composed of three parts. The carrier dispersant of colorant is mixed, crushed and extruded into granules by high-speed mixer. The masterbatch has obvious advantages such as high concentration, good dispersibility and cleanliness in the process of plastic processing.

Black masterbatch is a kind of color masterbatch. In short, it is a kind of pigmentation. Our black filler masterbatch is also one of them. It is used in the field for a long time. The light resistance and weather resistance of the coloring agent have a very important meaning. The chemical structure of the colouring agent is determined by its light resistance and weatherproof function, which replaces the basic type. So black filler masterbatch is also attributed to organic pigments, especially for azo and lake pigments, so its light resistance is poor. In addition, the colored plastics will undergo many changes in the future when exposed to light, such as oxidation, degradation reaction, which will directly affect the acceleration of the discoloration of the coloring agent. Most inorganic pigments have excellent light resistance.
