NCT Grade Purging Compound (Formerly Supernova™ HT)

NCT Grade is a chemical purging compound for high temperature resins, and is well suited for color and material changes for thermoplastic injection molding and extrusion machines. NCT grade can be used for sealing and shutting down machines to prevent carbon on start-ups.(Formerly Supernova™ HT)
arrow For High Temperature Resins arrow Polyethylene – Based
arrow Ideal for applications involving higher processing temperatures, and low flow or low pressure environments where foaming action is critical.
arrow Reduced foaming action to compensate for elevated temperatures.


Resins Purged:
Most engineering resins within the processing temperature range, above 175⁰C (350⁰F)

Tips when using ASACLEAN-N Series Chemical Purging Compound:

arrow Pre-purge with a stiff HMW-HDPE for difficult color/material changes.
arrow Soak 10-30 minutes, depending on specific application.
arrow No need to raise heats for high temperature applications.
