Pigments or dyes
Pigments are divided into organic pigments and inorganic pigments
Commonly used organic pigments include: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light-fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red, etc. Commonly used inorganic pigments include: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.
Carrier
It is the matrix of masterbatch. For special masterbatch, the same resin as the product resin is generally selected as the carrier. The compatibility between the two is the best, but the fluidity of the carrier must also be considered.
Dispersant
To promote uniform dispersion of pigments and no longer agglomeration, the dispersant should have a lower melting point than the resin, good compatibility with the resin, and good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular weight wax and stearate.
Additives
Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties. Unless the customer requests it, the above additives are generally not included in the color masterbatch.
