The application range of color masterbatch is very wide, as long as it is basically plastic is needed, sometimes in use, due to a variety of reasons exist, resulting in fading phenomenon, not only affect product performance, but also affect the coloring effect, then color masterbatch fading is mainly caused by what factors?

1. The light fastness of the colorant directly affects the fading of the products, outdoor products exposed to strong light, the light fastness grade of the colorant used is an important indicator, the light fastness grade is poor, and the products will fade quickly in use. Adding UV absorbent and other light stabilizer to the masterbatch can improve the light resistance of colorants and colored plastic products.

2. The degree of thermal weight loss, discoloration and fading of the pigment under the processing temperature of the color master.

3. The color master organic pigment is gradually faded due to the degradation of macromolecules or other changes after oxidation, one is high temperature oxidation, and the other is oxidation in the case of strong oxidants.

4. The fading of colored plastic products is related to the chemical resistance of the coloring agent.
