What are the components of black masterbatch

1. Pigments or dyes

Pigments can be divided into organic pigments and inorganic pigments. Commonly used organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, and light resistant bright red

Commonly used inorganic pigments such as macromolecular red, macromolecular yellow, Yonggu yellow, Yonggu purple, azo red, etc. include cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc

2. Carrier

The carrier is the matrix of black masterbatch, and specialized color masterbatch generally selects the same resin as the product resin as the carrier. The compatibility between the two is the best, but at the same time, the fluidity of the carrier should also be considered.

3. Dispersant

Promote the uniform dispersion of pigments without agglomeration, the melting point of dispersants should be lower than that of resins, and they have excellent compatibility with resins and good affinity with pigments. The most commonly used dispersants are polyethylene low molecular wax and stearate.

4. Additives

Additives. Such additives as flame retardant, brightening, antibacterial, anti-static, antioxidant, etc. are generally not included in black masterbatch unless requested by the customer.
