What are the basic ingredients of masterbatch?

1. Pigments or Dyes

Pigments are categorized as organic and inorganic.

Common organic pigments include: Phthalocyanine Red, Phthalocyanine Blue, Phthalocyanine Green, Sun-Fast Red, Macromolecule Red, Macromolecule Yellow, Permanent Yellow, Permanent Violet, and Azo Red. Common inorganic pigments include: Cadmium Red, Cadmium Yellow, Titanium Dioxide, Carbon Black, Iron Oxide Red, and Iron Oxide Yellow.

2. Carrier

This is the base of the masterbatch. For specialized masterbatches, the same resin as the final product is generally used as the carrier for optimal compatibility, but the carrier’s fluidity should also be considered.

3. Dispersant

This dispersant promotes uniform dispersion of the pigment and prevents agglomeration. The dispersant should have a lower melting point than the resin, good compatibility with the resin, and good affinity with the pigment. The most commonly used dispersants are polyethylene low-molecular wax and stearates.

4. Additives

These include flame retardants, brighteners, antibacterial agents, antistatic agents, and antioxidants. Masterbatches generally do not contain these additives unless specifically requested by the customer.
