Whats the basic composition of masterbatch
06/12/2018
The basic composition of masterbatch is:
1. Pigment or dye
Pigments are divided into organic pigments and inorganic pigments
Commonly
used organic pigments are: phthalocyanine red, phthalocyanine blue,
phthalocyanine green, fast red, macromolecule red, macromolecular
yellow, permanent yellow, permanent purple, azo red and so on. Commonly
used inorganic pigments are: cadmium red, cadmium yellow, titanium
dioxide, carbon black, red iron oxide, yellow iron oxide, etc.
2. Carrier
It is the matrix of masterbatch. The
special masterbatch generally chooses the same resin as the product
resin as the carrier, and the compatibility between the two is best, but
at the same time, the fluidity of the carrier should also be
considered.
3. Dispersant
To promote the
uniform dispersion of pigments and no longer agglomerate, the melting
point of the dispersant should be lower than that of the resin, and it
has good compatibility with the resin, and has a good affinity with the
pigment. The most commonly used dispersants are: polyethylene low molecular waxes, stearates.
4. Additives
