Use with Extrusion Machines:
Run the extruder with the natural grade of the plastic resin you are going to purge to remove the largest portion of the color (one time the content of the extruder)
If a screen pack is present, please remove it from the machine
Without running the extruder empty, load Ultra Purge and run machine at the same temperature as previous material (we recommend loading the quantity of 2 times the content of the barrel for machines that are in good working condition)
Adjust screw rotation to low to allow the compound to expand inside the machine. The ejected purging compound should have a foamy appearance. If it does not, further reduce the screw rotation speed.
*For larger extruders, allow Ultra Purge to soak for 3 minutes once it begins to eject out of the machine
When the previously loaded quantity of Ultra Purge is used up, load machine with the next production material. It important not to run the barrel empty to improve Ultra Purge’s performance
Begin normal production
