Material Notes:
Designed for Sheet & Profile ExtrusionGeneral Description:DYNA-PURGE X is a non-abrasive, non-chemical “engineered” thermoplastic purging compound, formulated to have a natural flow through the extruder. A non-melting but softening thermoplastic scrubs the screw and barrel, while the carrier matrix flushes away impurities. The material is designed for extruders and co-extruders that process tubing or pipe, sheet, and other profiles.FEATURES & BENEFITS OF DYNA-PURGE XExcellent for color changes, resin changes, preventative machine maintenance, and before manual cleaningDeveloped for purging through the barrel, die head, and other downstream equipment with a minimum clearance of .025 inch (.65 mm)Effective through a wide temperature range 320°F to 575°F (160°C to 302°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
