1. After using a certain plastic masterbatch, the product appears to be more susceptible to cracking.

This may be due to poor diffusion and miscibility caused by the poor quality of the dispersant or auxiliary agent selected by the manufacturer, which affects the physical and mechanical properties of the product.

2, the same color masterbatch, resin and formula, the color of the products injected by different injection molding machines has a shade

This is often caused by the injection molding machine. Different injection molding machines have different mechanical conditions due to different manufacturing, use time or maintenance conditions, especially the difference in the degree of adhesion between the heating element and the barrel, so that the dispersion state of the color master in the barrel is also different. A phenomenon will appear.

3, after changing the resin of another brand, the same color masterbatch and formula, the color has 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 color masterbatch will be different, resulting in color change. Generally speaking, as long as the density and melt index are not much different. , then the difference in color will not be too large, you can correct the color by adjusting the amount of plastic masterbatch.

4. Does the pigment masterbatch of the plastic masterbatch undergo storage during storage, will it 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.
