The fundamental components of black masterbatch may be well-known to most people who are familiar with plastic and plastic products. The processing of plastic products requires certain materials, and black masterbatch is crucial in plastic and plastic products. It is also a concern for many black plastic product companies, as some people do not fully understand plastic additives or some resin materials and other raw materials, The black masterbatch technology today mainly explains the four fundamental components of black masterbatch, which are expected to be helpful to us.

1、 Pigments or dyes

Pigments are divided into organic pigments and inorganic pigments. Commonly used organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, sun resistant bright red, macromolecular red, macromolecular yellow, Yonggu yellow, Yonggu purple, azo red, etc. Commonly used inorganic pigments 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 good, but at the same time, the fluidity of the carrier should also be considered.

3、 Laxative

Promote uniform dispersion and no longer agglomeration of pigments. The melting point of dispersants should be lower than that of resins, with good compatibility and affinity with pigments. The 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.
