Purging
Vol.20 #2, July 1993

To purge an extruder equipped with a gear pump, try heating the pump approximately 50o F over process temperature and flush with a chemical purge agent approved for use with your metallurgies, then follow up with LDPE or PP to complete the purge.

In most cases the processor can proceed directly with the next production run.
