COLOR CHANGE OR MATERIAL CHANGE?
Depending on the material that you are processing, we have different cleaning solutions.
In order to suggest the correct quantity and type of purging compound, it's very important to know which material is processed, the dimension of the screw and of the die, the percentage of masterbatch/pigments and the conditions of the machine.
