The basic components of the color masterbatch are:
1. Pigments or dyes Pigments are further classified into organic pigments and inorganic pigments. Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent Common inorganic pigments such as purple and azo red are: cadmium red, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow, etc.
2. The carrier is the matrix of the masterbatch. The special color master generally selects the same resin as the carrier resin as the carrier, and the compatibility between the two is the best, but the fluidity of the carrier is also considered.
3. The dispersing agent promotes the uniform dispersion of the pigment and no longer aggregates. The melting point of the dispersing agent should be lower than that of the resin, have good compatibility with the resin, and have good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular waxes, stearates.
4. Additives such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation, etc., unless the customer requests, in general, the color masterbatch does not contain the above additives.
