Basic knowledge of masterbatch

1. What is a masterbatch?

Color masterbatch is also known as color species. Color master batch (ColorMasterBatch) is a special colorant for new polymer materials, also known as pigment preparation (PigmentPreparation). It is composed of three basic elements of pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading super-constant pigment or dye in resin. It can be called Pigment Concentration, so his The tinting strength is higher than the pigment itself. To put it simply, a masterbatch is an aggregate made by evenly attaching a super-constant pigment or dye to a resin.

What are the basic ingredients of color masterbatch?

Th basic components of the color masterbatch are:

1. (KANGLIBANG Masterbatch) pigment or dye

Pigments are divided into organic pigments and inorganic pigments

kanglibang used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red, etc.

The commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

2. (kanglibang Masterbatch) carrier

The carrier is the matrix of the masterbatch. The special masterbatch generally chooses the same resin as the product resin as the carrier. The compatibility of the two is the best, but at the same time, the fluidity of the carrier must also be considered.

3. (Kang LiBANG color masterbatch) dispersant

Promote the uniform dispersion of the pigment and no longer agglomerate. The melting point of the dispersant should be lower than that of the resin, have good compatibility with the resin, and have a good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular wax and stearate.

4. (Kang LiBANG color masterbatch) additives

Such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation, etc., unless the customer requests, in general, the masterbatch does not contain the above additives.
