1. Pigment or dye
Pigments are also divided into organic pigments and inorganic pigments.
Common organic pigments are: phthalocyanine, phthalocyanine blue, phthalocyanine green, fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent violet, azo red, etc. The commonly used inorganic pigments are cadmium red, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow and so on.
2. The carrier
It is the matrix of the color masterbatch. The special color mother chooses the same resin as the product resin as the carrier, the compatibility of the two is the best, but also the liquidity of the carrier is also considered.
3. The dispersant
The melting point of dispersing agent should be lower than that of resin, and it has good compatibility with resin and good affinity with pigment. The most commonly used dispersants are: polyethylene low molecular wax, stearate.
Such as flame retardant, bright, antibacterial, antistatic, anti-oxidation and other varieties, unless the customer requests, in general the color mother does not contain the additive.
