General Information
Uses
  • Cleaning compound
Processing Method
  • Extrusion
  • Injection molding
Injection instructions
Empty barrel of production resin. Add PURGEX to hopper (a minimum of 1.5 times the injection capacity). Purge the barrel until PURGEX exits the nozzle. Soak for five minutes at processing temperature. Purge barrel to empty. Follow with next production resin, rinsing PURGEX from machine. Resume molding.
Extrusion instructions
Empty extruder. Remove screen. Seal vent. Fill extruder with PURGEX 459 Plus. Make certain extruder is full and PURGEX is exiting the nozzle as a foaming material. Soak five minutes at processing temperature. Add the next resin to be extruded and remove all PURGEX from the extruder. When it appears that PURGEX has been removed begin production.
