Brief Introduction to Color Masterbatch
1. What is a color masterbatch?
Color masterbatch is a collection of superconstant pigments (dyes) uniformly loaded into a resin.
2. What are the components of the color masterbatch?
Generally speaking, the color masterbatch mainly consists of three parts: colorant, carrier and dispersant.
Colorant: According to the color sample provided by the customer, choose the matched colorant that has a good affinity with the resin to be colored.
Dispersant: The main function of dispersant is to disperse the pigment into fine, stable and even distribution in the plastic, and no longer condense in the process.
At the same time, it has good compatibility with resin and does not affect the product quality. The melting point of dispersant should be lower than that of resin and have better affinity with pigment. Commonly used dispersants are: polyethylene low molecular wax, EVA wax, stearate, etc.
Carrier: The carrier is the base of the color masterbatch, making the pigment evenly distributed and making the color masterbatch granular.
The carrier should be considered to have good compatibility with the resin to be colored, and the color masterbatch should have good dispersion. Therefore, the fluidity of the carrier should be greater than that of the resin to be colored, and the quality of the product will not be affected after being colored.
3. What are the advantages of color masterbatch?
1). Make the pigment have better dispersion;
2). Keep the color of the product stable;
3). Avoid environmental pollution and ensure product color stability;
4) .Good quality and low product cost;
5). Simple color matching and operation, easy to use, good operating environment.
