Pigments or dyes
Pigments are divided into organic pigments and inorganic pigments
Common organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, sun resistant bright red, macromolecular red, macromolecular yellow, perpetual yellow, perpetual purple, azo red, etc. Common inorganic pigments include yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc
2. Carrier
It is the matrix of color masterbatch. Special colorants generally choose the same resin as the product resin as the carrier, which has the best compatibility between the two, but at the same time, the flowability of the carrier should also be considered.
3. Dispersant
To promote uniform dispersion of pigments and prevent agglomeration, the melting point of dispersants should be lower than that of resins, have good compatibility with resins, and have good affinity with pigments. The most commonly used dispersants are polyethylene low molecular wax and stearic acid salt.
4. Additives
Varieties such as flame retardant, brightening, antibacterial, anti-static, antioxidant, etc. are generally not included in the color masterbatch unless requested by the customer.
