1. Pigment or dye
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 violet, 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. Special color masterbatches generally choose the same resin as the product resin as the carrier, and the compatibility of the two is good, but at the same time, the fluidity of the carrier must be considered.

3. Dispersant
Promote the uniform dispersion of the pigment and no longer agglomerate. The melting point of the dispersant should be lower than that of the resin, and it has good compatibility with the resin and good affinity with the pigment. Commonly used dispersants are: polyethylene low-molecular wax and stearate.

4. Additives
Such as flame-retardant, brightening, anti-bacterial, anti-static, anti-oxidation, etc., unless requested by the customer, under normal circumstances the color masterbatch does not contain the above additives
