Purge and Shutdown Additives

Save lost time and reduce waste during clean outs

Purge masterbatches are designed to mildly scrub out your processing equipment during extrusion between jobs to accelerate old resin and colorant removal. Shut-down masterbatch is used to reduce the likelihood of polymer degradation from occurring due to your extrusion equipment.

Ampacet offers several purge and shutdown products to save time and reduce waste in processing. 

  • 100400 Purge PE masterbatch: a mildly abrasive transition purge for molding and extrusion equipment
  • NaturBlend™ 103828 Universal Purge: specially designed to purge out non-compatible materials such as polyethylene mixed with nylons
  • 100401 Antioxidant PE masterbatch: a shutdown compound designed to reduce oxidation of polyolefins remaining in the extruder during shutdown, start-ups and screen pack changes
