Material Notes:
Most versatile & widely used in the Plastics IndustryGeneral Description:DYNA-PURGE M is a versatile non-abrasive, non-chemical “engineered” thermoplastic purging compound, formulated to flow naturally through the barrel and hot runner system of the injection molding machine, as well as extrusion equipment. A non-melting but softening thermoplastic scrubs the screw and barrel, while the carrier matrix flushes away impurities.FEATURES & BENEFITS OF DYNA-PURGE MDeveloped for color changes, resin changes, preventative machine maintenance and before manual cleaningExcellent for purging through hot runner systems with a minimum clearance of .030 inch (.75 mm)Effective through a wide temperature range 350°F to 600°F(177°C to 315°C)Easy to use – no process adjustment necessary – use at the resident resin processing temperature and RPM speedNon-abrasive, non-melting but softening thermoplastic, which thoroughly loosens carbonized and degraded resin, allowing it to be flushed out of the systemSafe, non-hazardous, with no chemicals – ingredients are FDA compliantHeat stable – recommended during shutdown and start-upLow “cost-per-purge” – only small quantity needed to be effectiveNo mixing required – simply use “as is”Unlimited shelf life
