What problems do nylon masterbatch encounter in the production process?

1. After changing the resin of another brand, the color of the same color masterbatch and formula changed.

Different grades of resin will have different density and melt index, so the properties of the resin will be different, and the compatibility with the masterbatch will be different, so that color change occurs. Generally speaking, as long as the density and melt index are not different. Large, then the difference in color will not be too large, you can correct the color by adjusting the amount of color masterbatch.

2. Does the phenomenon of pigment migration during the storage of nylon masterbatch affect the quality of the product?

Some color masterbats have a high pigment content (or dye), and in this case, migration is normal. Especially the color masterbatch with dye added, serious migration will occur. However, this does not affect the quality of the product, because after the color master is injected into the product, the pigment is in a normal color development concentration in the product.

3. Why are some of the injected products not shiny?

There are many possibilities:

1. The nozzle temperature of the injection molding machine is too low

2. The mold finish of the injection molding machine is not good.

3. The molding cycle of the product is too long

4. Too much titanium dioxide contained in the masterbatch

5. The dispersion of the masterbatch is not good.
