1. Pigment or dye

Pigments are further divided 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 solid purple, azo red and so on. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow, etc.

2. Carrier

It is the matrix of the masterbatch. The special color masterbatch generally selects the same resin carrier as the product resin, and the compatibility between the two is the best, but the fluidity of the carrier is also considered.

3. Dispersant

The pigment is uniformly dispersed 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 and other varieties, unless the customer asks, in general, the color masterbatch does not contain the above additives.
