Product Description

Hi-Temp Purge Compound is Slide’s answer to those jobs where presses are run at temperatures between 485° and 750°F. This formulation aids with the purging of engineering-grade resins, and safely cleans screws and barrels with virtually no odor or smoke. It can remove burned material, color hang-ups, resin deposits, black specks and also soften and remove rust.

Hi-Temp is a chemically reactive, non-abrasive purge utilizing a PET carrier resin. While it is not recommended for cleaning hot runners, it is effective for use with injection molding and is ideal for resins such as PPS, PEEK, PET, LCP and PEI (Ultem™). All ingredients are GRAS rated so it is safe to use for food packaging applications. Use the online scheduler to set up a free consultation with one of Slide’s purging experts.
