1, the use of a masterbatch, products seem easier to rupture
This may be undesirable due to the manufacturers of the selected dispersing or poor quality due to diffusion aid solubility, affect the physical and mechanical properties of products.
2, after a period of time, and some plastics fading will occur.
Manufacturer basic pigments used poor quality, drift phenomenon.
3. Why ABS masterbatch particularly prone to color difference?
Countries produce different grades of ABS color, so even the same brand of ABS, each batch batch there may be color, the use of colored masterbatch of course there will be color. This is due to the characteristics of ABS due in the international community has not yet definitive solution. However, this color is generally not serious.
Users in the use of ABS masterbatch, must pay attention to this feature of ABS.
4, the same masterbatch, resins and formulations, different injection molding machine out of the product color shades why?
This is often caused by reason of injection molding machines. Different injection molding machine varies manufacture, use or maintenance of the status of the time, resulting in differences in the mechanical state, especially close to the degree of difference between the original heating and barrel, so that the dispersed state in the barrel in the masterbatch is not the same, the above phenomenon will appear.
5, after the change to another brand of resin, the same masterbatch and formulations, the color is changed, which is why?
Different grades of resin having a density and melt index will be different, so there will be differences in performance resins, and masterbatch compatibility will be different, so the color change occurs, generally speaking, as long as it is not a difference of density and melt index Great, so the color will not be much difference, you can adjust the amount of masterbatch to more positive color.
6, masterbatch occur during storage if the pigment migration phenomenon will affect the quality of the product?
Some masterbatch pigment content is high, in this case, the migration phenomenon is a normal occurrence. In particular dye is added masterbatch, serious migration phenomenon will occur. But this does not affect the quality of products, since masterbatch injection molded products, the pigment concentration in normal coloration in the article.
7. Why do some injection products luster bad?
There are a variety of possibilities:
1) injection molding machine nozzle temperature is too low
2) injection molding machine mold bad finish
3) products molding cycle is too long
4) contained in the titanium dioxide masterbatch excessive
