Pigments or Dyes
Pigments are further divided into organic and inorganic pigments.
Common organic pigments include: Phthalocyanine Red, Phthalocyanine Blue, Phthalocyanine Green, Fast Red, Macromolecular Red, Macromolecular Yellow, Permanent Yellow, Permanent Violet, Azo Red, etc. Common inorganic pigments include: Cadmium Red, Cadmium Yellow, Titanium Dioxide, Carbon Black, Iron Oxide Red, Iron Oxide Yellow, etc.
Carrier
This is the matrix of the masterbatch. Specialized masterbatches generally choose the same resin as the product resin as the carrier, as the compatibility between the two is best, but the carrier's flowability must also be considered.
Dispersant
This promotes uniform dispersion of the pigment and prevents further aggregation. The dispersant's melting point should be lower than the resin, it should have good compatibility with the resin, and good affinity with the pigment. The most commonly used dispersants are: low molecular weight polyethylene wax and stearates.
Additives
These include flame retardants, brighteners, antibacterial agents, antistatic agents, antioxidants, etc. Unless specifically requested by the customer, masterbatches generally do not contain these additives.
