Application of aluminum paste and pearlescent powder in masterbatch industry

1.Masterbatch = pigment + carrier + additive

2.Generally speaking, the carrier is a thermoplastic resin, which has good wetting and dispersing effects on pigments and has good compatibility. Masterbatch is currently the most common method for plastic coloring. The quality of masterbatch depends largely on the supply of raw materials such as pigments and dispersants.

3.Dispersant: It makes the pigment uniform and no longer agglomerates. The melting point of the dispersant should be lower than that of the resin, and it should have good compatibility with the resin and good affinity with the pigment. The most commonly used dispersants are polyethylene low molecular wax, stearate, etc.

4.Masterbatch classification by carrier:PE、PP、ABS、PVC、EVA
