  • Non-toxic, non-abrasive, and safe
  • Ready to use and easy to remove
  • Nylon purging compound
Features & Benefits
  • Created for more challenging color and/or material changes in engineering resins plus efficient cleaning of hot runner systems, Purgex 3057 Plus has the proven ability to clean low- to mid-range mineral- and PPO resins.
  • Designed for rapid turnaround on color and material changes. Efficiently removes residual contamination.
  • Purgex 3057 Plus effectively cleans the barrel, screw, check ring, as well as hot runner systems and is safely processed through hot runner gates as small as .030-inch (.75mm).
  • Thorough cleaning of melt pumps and is safely processed through dies as small as .030-inch (.75mm).
  • Active components in Purgex 3057 Plus neutralize acid gasses generated by PVC.
  • With regular use, Purgex forms a temporary barrier which protects steel surfaces from oxidation, extending the cleaning process.
