Purging Compound Basics
Purging compound, specifically commercial purging compound, is a product formulated specifically to clean thermoplastics molding machines and extruders. Purging compound is also used for color and material changes, removal of color and carbon deposits, as well as cleaning hot runners.
Ok...but can MY company use it?
Virgin resin, regrind, hand soap, laundry detergent – these may be used to purge, but they are most certainly not as effective as a commercial purging compound.
...but isn’t regrind free?
No it isn’t. In fact, it might be costing you more to use regrind than it would to use a commercial purging compound.

Aren’t they all the same?
