1. Pigment or dye
Pigments are divided into organic pigments and inorganic pigments
Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red, etc. Commonly used inorganic pigments are; cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.
2. Carrier
It is the matrix of masterbatch. The special color masterbatch generally chooses the same resin as the product resin as the carrier. The compatibility of the two is the best, but the fluidity of the carrier must also be considered.
3. Dispersant
To promote the uniform dispersion of pigments and no longer agglomeration, the melting point of the dispersant should be lower than that of the resin, have good compatibility with the resin, and have a better affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular weight wax, stearate.
4. Additives
Such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation and other varieties, unless the customer makes a request, the color masterbatch generally does not contain the above additives.
