What causes the color of the PP masterbatch to be uneven?

1. The melt of the PP masterbatch is lower than the melt of your base, and the finished product is not completely dispersed in your product.

2. Intention to replace the masterbatch of the high-melting finger. Try to mix the color masterbatch with your material as much as possible;

3. Be careful when choosing the color masterbatch. It is not the higher the melting index, the better, but the melting index is equivalent to the product you produce.

The above is the reason for the uneven color of the PP masterbatch.
