Instapurge Mechanical Purging Compound

InstaPurge is available in filled and unfilled forms and can be used with resins processed between 175-332°C.

InstaPurge F contains a chopped glass fibre material that provides additional “scrubbing” effectiveness for difficult purges.

InstaPurge U should be used in the following situations:

  • Hot runner systems
  • Extrusion systems unless the die and any screens or filters are removed
  • In systems that have internal flow passages of less than 1.0 mm
  • When the follow-on resin is of low viscosity (such as flexible PVC or LDPE) and might have difficulty displacing residues of the filled purging compound
  • When the added abrasiveness of the filler causes concern about wear on soft or polished metal finishes
