The Basic Components Of Masterbatches

1.Pigments or dyes
Pigments are further divided into organic pigments and inorganic pigments
Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, sunfast red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red and other commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc
2. Carriers
It is the matrix of masterbatches. The special masterbatch generally chooses the same resin as the product resin as the carrier, and the compatibility of the two is the best, but the fluidity of the carrier should also be considered.
3. Dispersants
To promote uniform dispersion of pigments and no longer agglomeration, the melting point of the dispersant should be lower than that of resin, have good compatibility with resin, and have good affinity with pigment. The most commonly used dispersants are: polyethylene low molecular weight wax, stearate.
4. Additives
Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless requested by customers, generally the masterbatch does not contain the above additives.
