by:TENGDA     2022-11-17

1. Pigments or Dyes

--- Pigments are divided into organic pigments and inorganic pigments

--- Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, macromolecular red, macromolecular yellow, permanent yellow, permanent violet, azo red, etc.

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

2. Carrier

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

3. Dispersant

---To 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, and it has good compatibility with the resin and good affinity with the pigment. Z commonly used dispersants are: polyethylene low molecular weight wax, stearate.

4. Additives

--- Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless the customer requests, under normal circumstances, the color masterbatch does not contain the above additives.

2 Varieties and grades of masterbatches

---The classification methods of color masterbatch are commonly used as follows:

---Classified by carrier: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc. Masterbatch Granulator

---Classified by use: such as injection masterbatch, blow molding masterbatch, spinning masterbatch, etc.
