NP Purge™ is an olefin-based purging compound. NP Purge is suitable for purging a wide range of commodity and engineering resins. When used as recommended, color and material change-over times are significantly reduced, eliminating much of the scrap material generated during the purge process.
NP Purge is non-abrasive and does not use an aggressive chemical reaction to efficiently purge both injection molding machines and extruders. After the recommended soak time, NP Purge’s reaction is complete and it will clean the previous material from the processing equipment before quickly being displaced by the next resin/color.
