The special color master generally selects the same resin as the carrier resin as the carrier, and the compatibility between the two is the best, but the fluidity of the carrier is also considered.
1. Dispersant Promotes the pigment to be uniformly dispersed and no longer aggregates. The melting point of the dispersant should be lower than that of the resin, have good compatibility with the resin, and have good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular waxes, stearates.
2. Additives Such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation and other varieties, unless the customer requests, in general, the color masterbatch does not contain the above additives.
