Features & Benefits

Materials Features

Non Abrasive,

Non-Toxic

Physical Description

• Blend, polyethylene, viscosity modifier and an active component
• Non-toxic, non-abrasive, and safe
• Ready to use and easy to remove

Features & Benefits

• Created for more challenging color and/or material changes plus efficient cleaning of hot runner systems, Purgex™ 457 Plus has proven to perform particularly well in removing low- to mid-range mineral- and glass-filled resins.
• Engineered for rapid turnaround on color and material changes. Efficiently removes residual contamination.
• 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 (0.75mm).
• Thorough cleaning of melt pumps and is safely processed through dies as small as .030-inch (0.75mm).
• Active components in Purgex™ 457 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.
